Dec 03, 2019

Essential Information

Students looking to complete an online biological science degree will find their options to be somewhat limited. There are schools offering undergraduate and graduate degrees alike, but these are relatively uncommon. Where they are available, programs may be found in online-only or hybrid formats.

Some undergraduate programs are designed with first-time students in mind, though many online bachelor's, master's and doctoral degree programs in biological science cater to the needs of working adults who would like to earn teaching credentials, change careers or develop their research skills while maintaining employment in a science-related field. To apply to a graduate-level program, students must hold a bachelor's degree, and they may need to have majored in biology as an undergraduate.

These programs allow students to access most or all of their coursework from home. On-campus requirements could include lab sessions, research symposia, proctored exams, student teaching internships or orientation sessions. Doctoral students are required to defend their dissertation in person.

Bachelor's Degree in Biology

Online undergraduate programs may award a Bachelor of Science or Bachelor of Arts in Biology, with the latter option including less quantitative math and science courses. Online biology curricula can also be available as a concentration within a natural sciences degree or as part of a teacher certification program designed for professionals with a science background. This latter option includes teacher education coursework in addition to biology courses covering the lab sciences, ecology, cellular biology and organismal biology.

Program Information and Requirements

Some biology degrees can be earned entirely online. Others require students to complete laboratory sessions on campus, though there are programs equipping students with lab kits that allow them to conduct experiments without having to leave home. Programs that prepare students for teacher certification require degree candidates to complete full-time student teaching experiences.

Course Topics

First-year coursework in an online biology program includes introductory classes in such areas as physics, chemistry, statistics and pre-calculus. Once students have completed these prerequisites they can enroll in core biology courses, some of which are outlined below.


Students in a genetics class examine the biological basis of heredity. They also explore factors influencing genetic variation as well as their quantitative and qualitative characteristics.


In addition to studying the effects of harmful bacteria, protozoa or fungi, students in this course examine the biological, industrial and agricultural applications of beneficial microorganisms. Students may also learn about microorganisms' roles in chemical transformations.


Course topics cover plants' cellular structure, metabolism and growth. Students also learn about the function of plant structures as well as the tools needed to conduct botany research.


An ecology course is primarily concerned with studying the effects of population size on the Earth's resources. Topics of discussion introduce students to the interactions between populations, species and the environment. Students can also look into factors determining an ecosystem's biodiversity.

Master's Degree in Biology

While a bachelor's degree in biological science is not always required to enter a master's degree program in the field, students who've completed some undergraduate biology coursework may be more likely to succeed in advanced classes. Online graduate programs in biology are designed to serve middle and high school teachers as well as other professionals. Topics of study range from evolution to immunology, and students often have the option of choosing between thesis and non-thesis options.

Program Information and Requirements

Master's degree programs in biology can be completed entirely online or through a combination of online and on-campus courses. Students interact with professors and classmates through methods that can vary with each course; some professors require participation in online discussion forums, while others hold live chats. Additional requirements could include the completion of proctored exams administered at on-campus testing centers.

Course Topics

Required courses for a master's degree in biology examine many different forms of life at the cellular and organismal level. Students also learn how organisms interact with each other to form complex ecosystems.

Animal Behavior

This course is focused on the behavioral adaptations of animals to their environment and the other species with which they share it. Master's degree candidates study how animals find shelter from predators and the elements, obtain food, select mates and raise their young.

Cell Biology

Students in this course examine the roles of various organelles within the cell. Students also learn the ways in which cells react to outside organisms, replicate DNA, reproduce and work in concert with other cells.


Courses in mycology introduce students to the uses of fungi in medicine and other fields. Classes cover the growth and reproduction of fungi as well as interactions between fungi and the environment.


This course introduces students to the relationships plant and animal species have with each other and their environment. Topics of discussion can also cover the conservation of fragile or threatened ecosystems.

Cancer Biology

Students in this course examine causes of cancer at the cellular level. They learn ways in which growth and metabolism are regulated in normal cells and how malfunctions in this regulation can lead to cancer.

Doctoral Degree in Biology

Online doctorate programs in the biological sciences allow students with a bachelor's or master's degree in biology - or a related field - to focus on such areas as conservation biology or industrial biochemistry and molecular biology. These programs are designed for professionals already working in rural planning, biotechnology, medicine or other fields requiring extensive research in the biological sciences. As a result, curricula include core courses that emphasize research methodologies along with electives that allow doctoral candidates to focus their studies on an area of interest.

Program Information and Requirements

Online doctoral biology programs require students to complete around 60-70 credit hours beyond a bachelor's degree. Course content can be delivered asynchronously or synchronously during the afternoons and evenings to accommodate the scheduling needs of working adults. Some programs also allow students to complete dissertation research on the job.

On-campus requirements for these programs could include an orientation before coursework begins or research symposia that take place twice each year. Students also need to present and defend their dissertation.

Course Topics

Core classes in these programs are designed to introduce students to their specialty area. The remaining coursework can be used to conduct independent research.

Research Problems

Students in this introductory course learn how to design experiments and gather research data. They could also learn how to evaluate and publish the results.


These courses can focus on bacterial, plant, human or animal genetics, depending on a student's specialty area. Topics of study cover the processes by which genetic material is reproduced in both prokaryotic and eukaryotic cells. Students examine recombination, DNA replication and gene regulation.

Structural Biology

This course covers such topics as ion channel structure and acid-protein interactions. Students also examine immune system components and learn how they relate to the discovery of new drug therapies.

Cell Biology

Students examine a cell's membrane structure and cytoskeleton. They might also study cell cycle regulation and signaling as well as protein targeting in animal cells. The functions of plant cell organelles could be discussed as well.

Career Information

Students who complete a biology program that includes teacher education coursework can pursue jobs as high school science teachers after earning state licensure. The U.S. Bureau of Labor Statistics (BLS) projected that employment opportunities for these secondary school educators would increase by 4% between 2018 and 2028.
