Answer #1

DNA is transcribed into mRNA during the transcription. The mRNA is complementary to the DNA. In mRNA, U is present in place of T.

A. The given DNA is TAC AAA TCT CAT TGT ATA GGA. The mRNA IS AUG UUU AGA GUA ACA UAU CCU. The amino acids will be Met-Phe-Arg-Val-Thr-Tyr-Pro.

B. If mutation occurs then the DNA strand will be

The mutant DNA is TAC AAT CTC ATT GTA TAG GA. The mRNA IS AUG UUA GAG UAA CAU AUC CU. The amino acids will be Met-Leu-Glu.

The UAA codes for stop codon so the peptide will abruptly end.

Suppose that the wild-type nucleotide sequence in the mRNA produced from a gene is 5'-AUGCCCUUUGGGAAAGGGUUUCCCUAA-3' Also, assume that a mutation is induced within this gene by proflavin and, subsequently, a revertant of this mutation is similarly induced with proflavin and shown to result from a second-site suppressor mutation within the same gene. If the amino acid sequence of the polypeptide encoded by this gene in...

1. Why can't transcription and translation of an mRNA occur at the same time in eukaryotes like it does in prokaryotes? In bacteria, translation of an mRNA can begin before its transcription is complete. mRNA synthesis begins at the 5' end and moves toward the 3' end.  After the 5' end is made, ribosomes can bind and begin translation. This coupling of transcription and translation does not occur in eukaryotes. Why not? 2. There is an amino acid that transfers its...
