Respuesta :
The statement 'eukaryotes use the 5′ G-cap and Poly-A-tail on their mRNAs to initiate translation' correctly describes one difference observed in eukaryotic and prokaryotic cells (Option c).
- In eukaryotes, the 5′ G-cap on the 5′ end of a messenger RNA (mRNA) molecule is a Guanine nucleotide linked to mRNA trough 5′-5′ triphosphate linkage.
- The poly Adenine tail (poly-A-tail) is a long sequence composed of repeated Adenine nucleotides in the 3' end of the mRNA.
- Both 5′ cap and the poly-A-tail act to protect the mRNA transcript from exonuclease (enzymatic) degradation and initiate translation.
In conclusion, the statement 'eukaryotes use the 5′ G-cap and Poly-A-tail on their mRNAs to initiate translation' correctly describes one difference observed in eukaryotic and prokaryotic cells (Option c).
