Question

There are four nitrogen bases in DNA so how many amino acids are present in peptides of human body?
a. 60
b. 20
c. 15
d. 20​

Answer 1

Answer:

Three nucleotides encode an amino acid. Proteins are built from a basic set of 20 amino acids, but there are only four bases. Simple calculations show that a minimum of three bases is required to encode at least 20 amino acids. Genetic experiments showed that an amino acid is in fact encoded by a group of three bases, or codon.There fore the correct answer is

{B}20

{D}20

20 amino acids are present in peptides of human body.

plz mark me as as the brainliest.

thnx

Take care
