Molecular biologists at one time proclaimed that
the central dogma of biology was that information
flowed only from DNA to RNA to protein. They
had to back down somewhat from this when it
was discovered that sometimes it could also go
from RNA to DNA (e.g. retroviruses).
Actually, if biology has anything that can be called
a "central dogma" it probably has to be evolution.
The fact of evolution was long ago established as
firmly as any historical fact can be. The theories
about how evolution works are still being discussed, and new mechanisms may still be
discovered. Saying that evolution is "just a theory"
is as fatuous as saying that Newton's theory of
gravity means that gravity is "just a theory" and
gravity doesn't really exist. The word "theory" has
different meanings in ordinary speech and in
science.

I would agree that the central dogma of ANY science would have to be scientific method, without it science is worthless.
As far as biology in particular, the subject is full of different studies it's hard to pick one that encompasses them all, but I'd have to go with Cell Theory. Cell Theory states that:
1 The cell is the fundamental unit of structure and function in living things.
2. All organisms are made up of one or more cells.
3. Cells arise from other cells through cellular division.
4. Cells carry genetic material passed to daughter cells during cellular division.
5. All cells are essentially the same in chemical composition.
6. Energy flow (metabolism and biochemistry) occurs within cells.

biology is the study of life and as such is a science. Dogma is a notion that is not to be disputed. As such i think there can't be a science dogma. it's sort of oxymoronic. Perhaps the closest thing would be simply that life exists, & therefore it can be studied. This is an excellent philosophical question.

I suppose that scientific method would be the central dogma of any true science, biology included. Scientific method may be the central philosophy of objective method, but it is nonetheless, a philosophy.

Biology is the branch of science dealing with the study of life. It is concerned with the characteristics, classification, and behaviors of organisms, how species come into existence, and the interactions they have with each other and with the environment. Biology encompasses a broad spectrum of academic fields that are often viewed as independent disciplines.

That refers to the idea that information in biological systems is stored in the form of DNA which is transcribed into RNA which is then translated to form proteins.
