According to this rule, the amount of adenine is equal to the amount of thymine, and the amount of guanine is equal to the amount of cytosine in a double-stranded DNA molecule. This 1:1 ratio of A:T ...

Both uracil and thymine pair with adenine, but they differ in their chemical structure. Thymine has an additional methyl group (-CH3) attached to its pyrimidine ring, while uracil lacks this group.

There are four types of base - adenine, thymine, cytosine and guanine ... and inheritance What is DNA and how is the structure of this hereditary molecule responsible for its function?

DNA is a linear molecule composed of four types of smaller chemical molecules called nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine ... The structure of DNA can also ...
