Lecture 2
The scope of biology is broad and therefore contains
many branches and subdisciplines.
Biologists may pursue one of those subdisciplines and
work in a more focused field.
The biological branches are divided according to the focus
of the discipline and can even be divided based on the
types of techniques and tools used to study that specific
focus.
With the increasing amount of basic biological
information growing due to advances in technology and
databases, there is often cross-discipline and
collaboration between branches.
Molecular biology and biochemistry study biological
processes at the molecular and chemical level,
respectively, including interactions among molecules such
as DNA, RNA, and proteins, as well as the way they are
regulated.
Microbiology, the study of microorganisms, is the study
of the structure and function of single-celled organisms.
It is quite a broad branch itself, and depending on the
subject of study, there are also microbial physiologists,
ecologists, and geneticists, among others.
Forensic science is the application of science to answer
questions related to the law.
