The first few triplets in one strand of a dna gene are, tacagacga the following amino acids are carried by trnas with the following anticodons: alanine trna anticodon is cga cysteine - trna anticodon is aca eucine trna anticodon is aau methionine - trna anticodon is uac proline trna anticodon is gga serine trna anticodon is aga the polypeptide chain produced by transcription and translation of this segment of the gene is composed of:
a. methionine, cysteine, proline
b. methionine, serine, alanine
c. alanine, cysteine, leucine
d. leucine, methionine, serine
e. none of the answers are correct.

The answer to your question is: B. methionine, serine, alanine

Explanation:

A. methionine, cysteine, proline  The first amino acid is correct but the others are not correct.

B. methionine, serine, alanine  All three amino acids are correct so, this is the correct answer.

C. alanine, cysteine, leucine  Only the second amino acid is correct, so, this answer is not correct.

D. leucine, methionine, serine the second and the third amino acids are correct but th order is wrong, so this answer is not correct.

E. None of the answers are correct. This answer is not possible because the option B is correct.

i believe the answer would be b. hope it : )
