How do the four nucleotides that make up DNA differ?

Answer 1

Adenine (A) and guanine (G) are purines.

Cytosine (C), Thymine (T), and Uracil (U) are pyrimidines.

Purines can only form hydrogen bonds with pyrimidines, and vice versa.

Therefore, the only base-pair bonds that can be formed are:

A-T

A-U

C-G

Answer 2

They are different because each base has a different shape, and they have different names.

Each DNA nucleotide contains one of four different nitrogen bases. They are adenine, thymine, guanine, and cytosine.

Answer 3

The four different nitrogenous bases; Adenine (A), Thymine (T), Guanine (G) and Cytosine (C) are the parts that are different on different nucleotides.

These bases differ in their chemical structure:

The pyrimidines, Cytosine and Thymine have one ring (with different side chains).

The purines, Adenine and Guanine have two rings (with different side chains).

Answer 4

The four nucleotides in DNA are adenine, thymine, cytosine, and guanine. They differ in their nitrogenous bases: adenine pairs with thymine, and cytosine pairs with guanine. This complementary base pairing forms the structure of the DNA double helix.

Answer 5

the chemical composition is very different. adenine will only connect to thymine, and guanine only connects to cytosine. almost an unlimited amount of combinations can be made!

Answer 6

differing only in the nitrogenous base
