Question

Which of the enzymes synthesizes short segments of RNA? A) I B) II C) III D) IV E) V A particular triplet of bases in the template strand of DNA is 5' AGT 3'.The corresponding codon for the mRNS transcribed is A) 3' UCA, 5'. B) 3' UGA 5'. C) 5' TCA 3'. D) 3' ACU 5'. E) either UCA or TCA, depending on wobble in the first base. A possible sequence of nucleotides in the template strand of DNA that would code for the polypeptide sequence phe-leu-ile-val would be A) 5' TTG-CTA-CAG-TAG 3'. B) 3' AAC-GAC-GUC-AUA 5'.

Explanation / Answer

Answer:

1) Which of the enzymes synthesizes short segments of RNA?

2) A particular triplet bases in the template strand of DNA is 5’ AGT 3’. The corresponding codon for the mRNA transcribed is:

3) A possible sequence of nucleotides in the template strand of DNA that would code for the polypeptide sequence phe-leu-ile-val would be:

The sequence that would code for the sequence phe-leu-ile-val would be 3' AAA-GAA-TAA-CAA 5' or any other combination containing allowable triplet code

Phe - AAA, AAG

Leu - AAT, AAC, GAA, GAG, GAT, GAC

Ile -TAA, TAG, TAT

val - CAA, CAG, CAT, CAC
