Question

1. In eukaryotes, transcription occurs in the nucleus, but post-transcriptional processing steps occur in the cytoplasm. (T or F)

2. The enzyme that catalyzes the formation of a peptide bond is called _________.

3. During translation, initiation the________ (which one) ribosomal RNA binds to the Shine Dalgarno Box. Give units.

4. In prokaryotes, the primary transcripts are the actual mRNAs. (T or F)

5. Suppressor tRNAs can suppress the effects of _______ mutations.

Answer 1

Answer 1 True

Answer 2 Peptidyl transferase.

The peptidyl transferase is an aminoacyltransferase as well as the primary enzymatic function of the ribosome, which forms peptide bonds between adjacent amino acids using tRNAs during the translation process of protein biosynthesis

Answer 3 small

Answer 4 True

they don't process mRNA by splicing, prokaryotes don't really have exons or introns.

Answer 5 nonsense' mutation

The mutation in the tRNA gene 'suppresses' the 'nonsense' mutation in the coding gene.​​​​​​​
