Molecular biology is the study of biology at a
molecular level. The field overlaps with other areas of biology and
chemistry, particularly genetics and biochemistry.
Molecular biology chiefly concerns itself with understanding the
interactions between the various systems of a cell, including the
interrelationship of DNA, RNA and protein synthesis and learning how
these interactions are regulated.
Writing in Nature, William Astbury described
molecular biology as
"... not so much a technique as an approach, an approach from the
viewpoint of the so-called basic sciences with the leading idea of
searching below the large-scale manifestations of classical biology
for the corresponding molecular plan. It is concerned particularly
with the forms of biological molecules and ..... is predominantly
three-dimensional and structural - which does not mean, however,
that it is merely a refinement of morphology - it must at the same
time inquire into genesis& function" |
