Answer:
C. Molecules such as cyclins are in high concentration in the cytoplasm of a dividing cell and will signal the fused cells nucleus to undergo mitosis
Explanation:
Various stages of the cell cycle are under tight regulation. Specific proteins such as cyclins and cyclin-dependent protein kinases determine if the cell would progress from one stage of the cell cycle to the next. When a cell is in the metaphase, the cyclins specific for mitosis are present in a higher amount in the cell. These cyclins bind to the specific CDKs and activate them.
The activated CDKs then phosphorylate proteins that make the cell to move through various stages of mitosis. Therefore, fusing a G1 cell with a cell in metaphase of mitosis would trigger mitosis in the G1 cell due to the presence of mitosis specific cyclins in the second cell.
Answer:
B Binary fission maintains genetic continuity because the daughter cells contain the same number of chromosomes as the parent cell.
Explanation:
Genetic continuity ensures that genetic information is passed from one generation to another in correct way so that the resultant progeny has the complete set of genes required for survival. For example, at the end of mitosis, daughter cells should have the same number of chromosomes as parent cell.
Binary fission is a method of reproduction in some organisms like bacteria. It is an asexual mode of reproduction in which the parent cell splits into daughter cells without the process of fusion with another cell. It still maintains genetic continuity because the daughter cells are identical to the parent cell and thus have same number of chromosomes and type of genes.
I believe the answer is sister chromatids in a chromosome.
To be exact 23 pairs of sister chromatids.
