<span>Senescence is about growing old. When one is very old, the body naturally deteriorates, and this includes the cells of the body which make up tissues and then organs. The daughter cells not being sustainable is a vital factor in the body gradually being unsustainable.</span>
Answer: Bacteria lack a mechanism for splicing out introns
Explanation:
Factor VII gene is 186k nucleotides long while the protein is 2332 amino acids long. <u>This lenght discrepancy is due to introns interrupting gene</u>, because the cell first transcribes the entire gene and then cuts introns out of the transcript. At the end, it splices the remaining pieces. Prokaryotes don't perform splicing so it can not edit out introns from the primary mRNA transcript. To produce an eukaryote gene in prokaryotes it is necessary to use a reverse transcriptase to get a cDNA sequence without the introns, and then insert that into a bacterial genome.
Answer: True
Explanation:
As the adolscent period progress more responsibilities are added into the life and the person needs to be mature and responsible.
