AUG is initiating codon. UCG codes for serine, UUU codes for phenylalan, UGU codes for cysteine.

Correct Option: A

AUG is initiating codon. UCG codes for serine, UUU codes for phenylalan, UGU codes for cysteine.

UAA is the stop codon. Therefore at 25th amino acid the synthesis of polypeptide stops. So, a polypeptide of 24 Amino acid is formed.

Correct Option: B

UAA is the stop codon. Therefore at 25th amino acid the synthesis of polypeptide stops. So, a polypeptide of 24 Amino acid is formed.

Out of a total of 64 codons, 3 codons do not make any sense. Hence only 61 codons are used in the formation of the 20 essential amino acids (polypeptides).

Correct Option: D

Out of a total of 64 codons, 3 codons do not make any sense. Hence only 61 codons are used in the formation of the 20 essential amino acids (polypeptides).

According to the Wobble hypothesis, tRNA anticodon has the ability to wobble at its 5′end by pairing with even noncomplementary base of mRNA codon. It correspond to third base degeneracy of the codons.

Correct Option: A

According to the Wobble hypothesis, tRNA anticodon has the ability to wobble at its 5′end by pairing with even noncomplementary base of mRNA codon. It correspond to third base degeneracy of the codons.

Eukaryotes have three types of RNA polymerases:
(i) RNA polymerase I - It is found in nucleus and is responsible for r-RNA synthesis.
(ii) RNA polymerase II - It is found in nucleoplasm and is responsible for m-RNA synthesis.
(iii) RNA polymerase III-It is found in nucleoplasm and is responsbile for t-RNA and 5-S RNA synthesis.
