Question

#8 - The Genetic Code
18. How many amino acids are involved in the production of proteins?

Answer 1

#18: Polypeptide chains contain one of 20 different amino acids at each position.

Step-by-step explanation:

So 20.

Answer 2

Answer: 20 amino acids

Step-by-step explanation:

The Genetic code permits the triplet nature of codons whereby three nucleotides from Adenine, Uracil, Guanine and Cytosine on the messenger RNA (mRNA) join to form 64 codons.

Since more than one codon can specify for an amino acid, the 64 codons then specify for 20 amino acids, that then form the sequence of various proteins
