Question

1. Select all the of the statements below that apply to both eukaryotic and bacterial gene expression?

Bacteria and eukaryotes can have 70S ribosomes.

Bacteria and eukarytoes may have genes organized and regulated within operons.

Bacteria and eukaryotes have 70S ribosomes in their cytoplasm.

Initiation of translation in bacteria and eukaryotes occurs when the ribosomal subunit binds to the 5' guanine cap.

Bacterial and eukaryotic mRNA is modified prior to translation.

Answer 1

ANS) bacteria and eukaryotic mRNA modified prior to translation.

Because,RNA molecules play many role in regulating gene expression in eukaryotes.Eukaryotic mRNA molecule must be completed,formed and must pass across the nuclear membrane before translation.

other statements are not in both eukaryotic and bacterial gene expression:

1)70s ribosomes are usually present in prokaryote.eukaryotes have 80s ribosomes with some expressions like mitochondrial and chloroplast.

2) initiation of translation in prokaryote.

3) bacterial genes are organised into operon or clusters of correlated genes.and physically closed in the genome.
