Answer:
Option A, helps prevent rapid breakdown of the messenger RNA
Explanation:
The poly-A tail is a chain of adenine nucleotides which when get attached to the messenger RNA during RNA processing enhances the stability of the molecule and therefore prevents it from breaking down. This is required because after the transcription of gene in a eukaryotic cell, newly formed RNA molecule undergoes several modifications. It also helps is preventing the new RNA from enzymatic degradation in the cytoplasm and translation.
Hence, option A is correct

Answer:
Ribosomes link amino acids together in the order specified by the codons of messenger RNA molecules to form polypeptide chains. The function of ribosomes is to make proteins for the cell.
Answer:The molecules of chlorophyll contained in the chloroplasts absorb energy in the form of light from the sun. Some plants need more sunlight than others, but all need at least a little. Instead of taking in oxygen and breathing out carbon dioxide like animals do, plants take in carbon dioxide from the atmosphere......thank you.have a great day
Answer:
See the answer below
Explanation:
The acidification of stomach juices is important for the digestion of proteins partly because the enzyme responsible for protein digestion work in an acidic medium and the acid also facilitates the unfolding of the proteins.
Hydrochloric acid and the enzyme responsible for the initiation of protein digestion, pepsin is secreted as gastric juice by the stomach, and the latter works by breaking down protein chains into smaller fragments.
