Of all possible amino acids, all living organisms make use of only 20 amino acids. this supports the idea that

Solution:

Because amino acids can be arranged in many different combinations, it's possible for our body to make thousands of different kinds of proteins from just the same 21amino acids. There are only 20 amino acids.

The 20 Amino acids which make proteins are:

•alanine - ala - A (gif, interactive)

•arginine - arg - R (gif, interactive)

•asparagine - asn - N (gif, interactive)

•aspartic acid - asp - D (gif, interactive)

•cysteine - cys - C (gif, interactive)

•glutamine - gln - Q (gif, interactive)

•glutamic acid - glu - E (gif, interactive)

•glycine - gly

Thus this is the required answer.

step 1: replication fork formation.

step 2: primer binding.

step 3: elongation.

step 4: termination.
