Question

Select all of the following which are Nitrogenous bases that make up DNA:

a)Glutamine

b)Thymine

c)Adenine

d)Thyrine

e)Guanine

f)Cytosine

Answer 1

adenine (A, green), thymine (T, red), cytosine (C, orange), and guanine (G, blue).

Step-by-step explanation:

The nitrogen bases in a DNA molecule are adenine, guanine, cytosine, and thymine. Adenine and guanine belong to a class of compounds called purines, and cytosine and thymine belong to a class of compounds called pyrimidines. In a DNA molecule, the two strands are connecting by hydrogen bonds between the nitrogen bases of each strand. According to the base-pairing rule, the purine adenine always pairs with the pyrimidine thymine, and the purine guanine always pairs with the pyrimidine cytosine...
