Bachelor of Science in Biology

Study the Science of Life with an On-Campus or Online Bachelor’s Degree in Biology

Pursue a foundational knowledge of life sciences with a Bachelor of Science in Biology (BS in Biology) from Post University. Offered both online and on our main campus, our program for a bachelor’s degree in biology provides the opportunity to design and conduct experiments; develop your scientific and quantitative reasoning skills; collect and organize data for analysis; and hone your written and oral communication skills through lab reports and in-class presentations over many subspecialties of biology. Your biology major also offers the opportunity to explore molecular biology, cellular biology, microbiology, genetics, botany (plant biology), anatomy and physiology, zoology, and ecology.

What Could I Do with a Bachelor’s Degree in Biology?

Coursework for your degree in biology covers the essentials of this field of science, including evolution, cellular structure and function, genetics, bioenergetics, and interacting systems. The program is designed to help refine your understanding of the scientific process. It demonstrates how to use quantitative reasoning to describe biological phenomena. It also dives into modeling and simulation, scientific communication, and ethics. In addition to core coursework, you will need to complete an independent study project or internship.

Your Bachelor of Science in Biology program offers the opportunity to build the skills and knowledge base often used within health science, research, education, biotech, and life science settings. The insights and information it covers could help prepare you for relevant entry-level positions that require a fundamental understanding in biology or for post-graduate degree programs, depending on relevant admissions requirements and your goals.

​Industry-Focused Curriculum for Professional Skills

Coursework for your BS in Biology is designed to help you develop professional skills in:

  • Biology — applying principles of biology for evolution, structure and function, genetics, bioenergetics, and interacting systems
  • Scientific Inquiry — formulating hypothesis and interpreting results
  • Quantitative Reasoning —defining biological phenomena accurately
  • Modeling — describing complex systems and making predictions
  • Scientific Communication — using scientific terminology and conventions to communicate with other scientists

Biology Program Concentrations

In addition to core coursework in biology fundamentals and scientific principles, you will have the opportunity to customize your degree to your future goals with one of these three concentration options:

General Biology — Campus and Online

With one-on-one guidance from a dedicated student success advisor, this concentration allows students to focus on specific areas of interest—such as molecular biology, cellular biology, or microbiology—with relevant upper-level electives.

Bioinformatics — Campus and Online

With coursework in statistics, data structure, and genomics, the concentration in bioinformatics focuses on applying structure and statistical analysis in support of scientific inquiry for biological data.

Health Sciences — Campus Only

This concentration offers lectures and labs for an introduction to health sciences in physiology—exploring skeletal, muscular, and nervous systems—as well as the structure, function, and classification of microbes, microbial diseases, and responses from immune systems.


​Benefits of Earning a Bachelor’s Degree in Biology Online

From the admissions process to the day you graduate, we are with you every step of the way.

  • Receive support from a personal Post team of advisors focused on your academic success
  • Learn from industry-experienced professionals in interactive courses
  • No class times or set login times for your online biology degree program
  • Online courses emphasize practical understanding of biology fundamentals

Note: Students considering pursuing a Pre-Health Track within their biology degree program should weigh the benefits of online learning carefully, as online coursework may not be accepted for entry into a medical or veterinary program.

​A Word from Our Program Chair​

“With science and biology, there are always new things coming out. The field is continually advancing. The biology program is going to provide you with the background knowledge that you could use to be successful in a science position. As soon as we start, we are in the lab, you are learning the technical skills to be able to think like a scientist.”

Carla Goldstone, MS
Program Chair, Biology

What is a biological sciences major?

A biological sciences major delves into the study of living organisms and their interactions with the environment. It covers a broad spectrum of disciplines, including molecular biology, genetics, ecology, physiology, microbiology, and evolution. This major provides a comprehensive understanding of life at different levels, from molecules and cells to organisms and ecosystems.

How long does it take to get a biology degree?

Typically, it takes about four years to complete a Bachelor of Science (BS) in Biology. However, the duration may vary depending on factors such as the program structure, credit requirements, and whether you choose an accelerated track or pursue the degree online. Some students may take longer if they opt for part-time study or if their program includes co-op or internship experiences.

What do you study in biology?

In biology, students study the structure, function, evolution, and interactions of living organisms. They study topics such as cell biology, genetics, ecology, evolution, physiology, microbiology, and biodiversity. Through laboratory work, field studies, research projects for on-campus learners, and simulations for online learners, students have the opportunity to develop practical skills in scientific inquiry, data analysis, experimental design, and critical thinking. Biology education also emphasizes interdisciplinary connections with chemistry, physics, mathematics, and environmental science.

What classes does a biology major take?

Biology majors typically take a range of core courses covering foundational concepts in biology, including general biology, cell biology, genetics, ecology, evolution, and physiology. Depending on their interests and career goals, students may choose elective courses in specialized areas such as microbiology, molecular biology, plant biology, animal behavior, or bioinformatics. Advanced coursework may include seminars, independent research projects, or internships tailored to individual interests.

Can you earn a bachelor’s in biology online?

Yes, you can pursue a bachelor’s degree in biology online through Post University. The program is designed to provide a comprehensive understanding of biology through a flexible and convenient online format. Online students have access to the same curriculum, faculty support, and resources as on-campus students. This allows individuals to pursue their education while balancing work, family, or other commitments.

What is the hardest class while getting a biology degree?

Advanced biology classes like Genetics, Biochemistry, Genomics, Cell Biology, and Anatomy and Physiology are often considered challenging due to their complex subject matter and rigorous coursework. These courses require a deep understanding of biological principles, strong analytical skills, and the ability to integrate knowledge from various disciplines. However, they also provide valuable insights into key biological processes and contribute to a well-rounded education in biology.
