Biology Career Guide

What to Expect in a Bachelor's in Biology Program

Online biology degrees generally require approximately 120 credits to graduate, one-third of which typically relate to the major. In the other 80 credits, students take general education courses and can usually complete a minor or second major. Many online biology degrees also allow learners to choose a concentration in a biology subfield (e.g., marine biology). In their junior or senior year, students complete a capstone project. Capstone project requirements vary among programs but can include a graduate-level course or research project.

With so many careers that biology graduates can pursue, degree-seekers should start researching career paths as soon as possible. Some careers (e.g., physician) require 2-4 years of additional education. Other positions may ask applicants to possess relevant work experience. For this reason, distance learners should research internship opportunities in their community.

Online biology degrees often require the following five courses or similar classes. Course titles and academic content can vary among programs.

General Biology

This foundational course introduces students to many biology topics, including DNA, RNA, and how cells function. Most programs require that students complete a general biology course in the first semester.

Anatomy and Physiology

Another introductory course, anatomy and physiology concerns the human body's systems (e.g., muscles, the skeleton). Students planning to enter medical school usually take multiple courses on this topic.

Organic Chemistry

Organic chemistry describes how chemical reactions drive living organisms. Typically, biology students take two organic chemistry courses. Before starting organic chemistry, students must first pass an introductory course in chemistry.


In a genetics course, learners analyze the science behind the ways living organisms pass down traits. Course topics include Gregor Mendel's contribution to the field, replication, and gene mapping.

General Physics

This course provides students insight into how physical laws influence living organisms. Learners apply algebra and trigonometry concepts to gain a better understanding of physical laws.

Secretary at Fundación Manos Juntas

Portrait of Jackson Higginbottom

Jackson Higginbottom

Jackson Higginbottom is a first-year master of public health (MPH) candidate in social and behavioral sciences at the Yale School of Public Health (YSPH). Jackson is originally from Oklahoma, where he studied biology as an undergraduate and worked with marginalized populations in various clinics within Oklahoma City. Prior to coming to Yale, he worked with a nonprofit organization in Guatemala to provide sustainable healthcare to K'iche' communities.

Jackson currently serves as secretary of the board of directors at Fundación Manos Juntas, the largest free medical clinic in Oklahoma City. Jackson also researches evidence-based approaches to improving mental health and reducing stigma at the ESTEEM Laboratory at Yale, and he works as a research assistant at Yale's Community Alliance for Research and Engagement (CARE). He is a representative on the YSPH Student Diversity Committee through his role on the Out in Public board. Jackson is interested in understanding how social interactions impact personal and community health behaviors.

Why did you choose to pursue a bachelor's in biology? Was this a field that always interested you?

Ever since I can remember, I wanted to become a doctor. I had the notion that the only path to medical school was through a biology program. I had always excelled in the sciences growing up, so I did not have any second thoughts about pursuing this degree. The deeper I got into my core courses, the more fascinated I was by the intricacies of life. Despite the difficulty of my classes, I was always able to appreciate how necessary these fields were to my future career.

What would you say are some of the most crucial skills you gained in your biology degree program? How do those skills apply directly to your day-to-day work?

I believe perseverance and the willingness to make mistakes are some of the most crucial skills I gained during my biology degree program. Many biology programs have a reputation for being "cutthroat" due to the misguided belief that medical schools require a perfect GPA, recommendation letters from esteemed professors, and an exorbitant amount of research experience. This belief is perpetuated by professors who weed out students they deem unworthy of medical school due to their inability to use the appropriate number of sig figs (significant figures) in scientific calculations or poor pipetting skills in the lab.

However, my school encouraged us to make mistakes in the laboratory by having a hands-off approach to the various exercises we were conducting. This enabled us as students to gain a better understanding of the material and mechanisms at work and simultaneously develop problem-solving skills. I learned that it is okay to make mistakes, but only if you can recognize and address those mistakes before moving forward.

I am currently working in the ESTEEM Laboratory at Yale, which researches evidence-based approaches to improving mental health and reducing stigma. Our research involves human participants, which requires extreme attention to detail and confidentiality to minimize the risk of harming our participants. If I were to make a mistake and try covering it up, it could harm our participants, endanger our research, and impact my career. However, if I were to make a mistake and reported it immediately, I would be able to minimize any damage that had already been done, protect our research, and save my career. We are human; it is okay to make mistakes.

What did you learn from your experiences working with marginalized populations in Oklahoma City? How did that shape the rest of your career?

It was within clinics, like Fundación Manos Juntas and the Lighthouse Medical Clinic, that I was able to connect with patients from many different backgrounds and hear their stories. On several occasions, I sat next to healthcare providers explaining to patients how their illness is merely a consequence of an unhealthy lifestyle or poor behaviors. I have since learned that many diseases -- chronic and acute -- could have been prevented through proper health education.

Unfortunately, not every population receives the same education and support with regards to their health. These inequities are magnified upon examination of the health disparities that plague minority groups and low-income populations. As a pre-med biology student, I was not exposed to these issues in my formal biology education. My biology professors often frowned upon the amount of time I spent volunteering in free clinics. However, without these experiences, there would be a large gap in my understanding of health.

Recognizing and understanding the social and structural determinants of health changed my career path, at least temporarily, from medical school to public health. I would not be at the Yale School of Public Health if I had listened to my professors and stopped volunteering in my community. Each patient story challenged my misconceptions, expanded my mind, and instilled a passion for working with vulnerable populations.

What advice would you give to biology students who are debating whether to earn their degrees online or on campus?

I would urge students to determine how much accountability they require to actually complete the readings and assignments. Some students need the competitive or collaborative atmosphere of on-campus biology programs. If I had chosen an online degree as a freshman in undergrad, I am not certain I would be where I am today. This is because I had not developed essential skills, like time management or how to organize my classes (much less myself).

What advice would you give to biology students who want to get the most experience they can out of their studies? What types of extracurricular activities, internships, etc. should they consider during college?

Regardless of the format you choose, do all of the readings. Get involved with extracurriculars and gain leadership experience. Get involved in your local community and attempt to make a difference in an area you are passionate about.

It is okay to not be the stereotypical biology student. Take classes outside of your department and make friends in different fields. Take chances and be willing to make mistakes. Take care of your health, first and foremost. I always suggest students make an appointment to see a counselor at the beginning of each semester, just as you would get a checkup with your doctor. It is good to touch base with these resources and to feel comfortable with accessing them before ever needing them.

Any final thoughts for us?

Try new things, especially if you think you won't like them. I never thought I would enjoy formal research, much less social sciences, but here I am studying social and behavioral sciences at the Yale School of Public Health, working in two research labs, and learning SAS and R statistical programming.

How to Choose a Bachelor's in Biology Program

All online biology degrees you apply to should possess regional accreditation, which demonstrates adherence to quality standards. There are six regional accrediting agencies around the country.

Although not all the best programs boast programmatic accreditation, pay close attention to those with accreditation from the American Institute of Biological Sciences or the American Society for Biochemistry and Molecular Biology. These agencies employ experts to review programs' curricula. Finally, if a master's or doctoral program in biology holds accreditation from either of these agencies, you can infer that the school's bachelor's program also possesses excellent academic qualities.

Here are some other factors to keep in mind.

  • Laboratory Coursework: Most online biology programs either send students material so they can complete laboratory experiments at home or ask them to attend in-person labs at a local school.
  • Internships: Online schools for biology degrees should connect students with internship opportunities. An internship can make degree-seekers an attractive graduate school or job applicant.
  • Student Services: Even experienced online learners need student support services. Before applying to a program, research its tutoring, career, and IT services that help online students succeed.
