Question

Which of the following processes occurs in eukaryotic gene expression?RNA polymerase requires tRNA to elongate the molecule.mRNA, tRNA, and rRNA are translated.A cap is added to the 5 end of the mRNA.RNA polymerase binds to the terminator sequence.

Answer 1

Answer:

A cap is added to the 5 end of the mRNA

Explanation:

In prokaryotes, the translation process takes place simultaneously with the transcription but the mRNA molecule after synthesis undergoes some post-translation modification which protects the mRNA from the cytosolic environment.

One of these modifications is known as capping which refers to the addition of the cap at 5' end of the mRNA. This cap is added by an enzyme called guanyl transferease and protects the end of the mRNA.

Thus, the selected option is correct.

Answer 2

During eukaryotic gene expression, a protective cap is added to the 5' end of the mRNA.

The eukaryotic gene expression starts by transcription. Genetic information on the DNA is transcribed into genetic codes as mRNA.

Thereafter, the pre-mRNA generated undergoes some processings which include the addition of a protective cap to the 5' end and a poly-A tail to the 3' end.

The processed mRNA is then transported from the nucleus to the cytoplasm where it gets translated into a protein.
