Answer:
The correct answer is A When dTTP is bound to the specificity site, more dCDP is produced
Explanation:
Ribonucleotide reductase catalyzes the conversion of ribonucleotide to deoxyribonucleotide.
When dTTP is bound to the specificity site at that time dCDP is produced.The So formed dCDP is converted to dUDP by the help of dCDP deaminase.The dUDP is then converted to dUTP by phosphorylation.
Finally the dUTP is converted to dTTP by the catalytic activity of thymidylate synthase with the presence of N5 N10 methylene tetrahydrofolate.
Thus equal amount of deoxyribonucleoside triphosphates are maitained by the cell.
Answer:
abnormal development or growth especially of cells.
Answer:
"Last week, you looked at both animal & plant cells. Both of these cells were diploid somatic eukaryotic. This week, you'll be looking at a different, but very important, type of cell: sexual cells. Two gametes, one from a female & one from a male, merge during the process of fecundation/fertilization to form a zygote. All in the organism will develop from this initial diploid cell".
Explanation:
There are two principal types of cells in the organism: Somatic cells that can not form any gametes, and germ cells that are in charge of gamete production. Both somatic cells and germinal cells will end their cycle dividing and becoming two daughter cells with the same genetic dotation after mitosis.
Somatic cells are any cell in the body excepting from sperm and egg cells. These somatic cells are diploid, they contain two chromosomes sets, each one inherited from each parental. Mutations in somatic cells affect the individual but the progeny does not inherit them. In this sense, these cells do not contribute to anything to inheritance terms through genetics.
Germ cells are the reproductive diploid cells, and the sexual organs (testes and ovaries) are the ones that produce them. These cells might suffer mitosis to form more sexual cells, and then a few of them suffer meiosis giving place to haploid gametes called sperm and egg cells through the gametogenesis process. Each germ cell produces 4 haploid gametes after meiosis.
Gametes´destiny is to merge in the process of fecundation, during which a new diploid cell called zygote emerges through fertilization. The zygote is a complete cell from the structural point of view that suffer successive mitosis to form the new organism.
Answer: Mitosis
Explanation:
Mitosis is one of the two types of cell division alongside meiosis. All the cells in the body undergo mitosis except sex cells such as male sperm and female ova that undergoes meiosis during sexual reproduction.
Thus, since mitosis occur in body cells, most of the cells in humans are body by it.
