DNA is regarded as the
information-carrying molecule.
Cells contain the DNA material that carries genetic
information of an organism.
One cell has trillions of
chromosomes which store the
DNA molecule in the nucleus.
The backbone of the DNA comprises
of alternating sugar-phosphate groups.
The two backbones are held together by
complementary base pairing of the
nitrogenous bases through hydrogen
bonding.
The repetitive basic building blocks of DNA which
consists of three components.

There are four bases:
adenine (A), thymine (T), cytosine (C) and guanine (G)
A complimentary binds with T.
C complimentary binds with G.

These two scientists were
known to discover the
twisted ladder structure of
life.
However, it was Franklin who
discovered the structure of the DNA
first before Watson & Crick.
Photo 51 remains as the most crucial
evidence of her findings towards the
discovery of DNA.
