Answer:
The correct answer is B 4 cells are formed,each having half the number of chromosomes as the original cell.
Explanation:
Meiosis is a specific type of cell division that occur in the germ cells.Meiosis is called reductional division because the 4 new cells those are produced after second meiotic division contain half the number of chromosomes as that of original cells.
During meiosis a cell undergo division two times the division that occur during first time is called first meiotic division resulting in the formation of 2 cells having 2n number of chromosomes.On the other hand the second meiotic division form 4 cells each having half the number of chromosomes.
Insulin is a hormone produced in the pancreas (gut) .
Function:
Insulin regulates the amount of glucose in the blood. The lack of insulin causes a form of diabetes.
Answer: Transcription initiation
Explanation:
In genetics, a promoter is a region of DNA that leads to initiation of transcription of a particular gene. Promoters are located near the transcription start sites of genes, upstream on the DNA (towards the 5' region of the sense strand).
Depending on the location and the nature of the genetic defect, ( for example if the sequence TTGACA has been lost), a mutation in the promoter region of a gene may disrupt the normal processes of gene activation by disturbing the ordered recruitment of TRANSCRIPTION FACTORS (TFs) at the promoter.
RNA polymerase || is just the main transcription enzyme.
