Answer: diabetes mellitus
Explanation:
This is a disease condition associated with elevated blood glucose levels.
It is due to abnormalities of the Pancreas. The pancreas coordinates two hormones INSULIN AND GLUCAGON in its cells.
INSULIN converts excess sugar to GLYCOGEN while GLUCAGON breaks down GLYCOGEN to sugar when blood glucose/glucose levels drops.
If the pancreas beta-cells of glucose are faulty, INSULIN fails to converts excess glucose to glycogen; therefore glucose builds up in the blood plasma,and failed to enter the needed cells. Large amount of glucose is wasted in urine.This is diabetes Mellitus.
The two types of diabetes are:
Type 1 and Type 2.
Answer: Option E -- RNA Editing
Explanation:
It should be noted that, RNA editing can be defined as a molecular process via which some cells can make discrete changes to specific nucleotide sequences within an mRNA molecule after it has been generated by RNA polymerase. In addition, we have two major types of RNA editing with 1 being a C-to-U change catalyzed by cytidine deaminase that deaminates a cytidine base into a uridine base, e.g C-to-U editing is with the apolipoprotein B gene in humans. ApoB-100 is expressed in the liver and apoB-48 is expressed in the intestines. The B-100 form comprises of a CAA sequence that is edited to UAA, a stop codon, in the intestines.
The question is incorrect so the answer consists of the genetic context of meiosis.
Answer:
Two main types of cell division are mitosis and meiosis. Meiosis is the process of cell cycle division in which the parents cell divides into the four daughter cells. This division is also known as reductional division.
In meiosis, the gametes are haploid where as the parent cell is diploid in nature. The cell undergoes the two meiosis division, the first division is reductional in nature whereas the second meiosis division is same as the mitotic division. This division occurs in the sex cells and results in the formation of haploid gamete hat restores deiploidy during fertilization process. Crossing over during meiosis bring variation in the cells.
