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:
a human can stay up to 79 years
The answer is b, decrease the oxygen gas pressure
<span>E. All of these are correct
A normal, typical and functional cell undergoes cell cycle in normal fashion and eventually reaches apoptosis. Yet cancer cells fail to display just some of these characteristics.
</span><span>The cycle cycle; mitosis occurs more in your body since it changes, modifies and requires cell division at maximum rate in many useful situations with the stand to a particular system and organ. Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells.</span>
