Answer:
Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells.
The correct answer is: The addition of a 7-mG cap at the 5' end of the transcript and the addition of a poly-A sequence at the 3' end of the message
These posttranscriptional processes are called:
• 5’ capping - It protects the mRNA from 5' degradation by exonucleases. Cap is also involved in ribosomal binding.
• Polyadenilation or addition of poly(A) tail – It also protects mRNA from degradation of 3’exonucleases. A long poly(A) tail can also increase translation.
This macromolecule would best describe a a polysaccharide, a polymer of monosaccharides.
