The basic unit of structure and function found in all living things is cell. They provide structure to your body
Answer:
The embryo passes through multiple rounds of the cell cycle, but cytokinesis does not occur during M phases.
Explanation:
The cell cycle includes a series of events that make new cells from the existing cells. During the process, nuclear division during the M phase produces daughter nuclei. Nuclear division is followed by cytokinesis. Cytokinesis is the division of cytoplasm and results in the formation of daughter cells.
If a cell undergoing cell cycle forms daughter nuclei by mitosis, all the daughter nuclei are genetically identical. In the absence of cytokinesis, cytoplasm would not divide and the daughter nuclei will remain in the parent cell only. Repeated nuclear division without cytokinesis would produce multiple nuclei present in the parent cell.
Answer: option B - some gametes may have an extra copy of some genes.
Explanation:
Actually, nondisjunction occurs in meiosis and results in FOUR ABNORMAL GAMETES/DAUGHTER CELLS: two gametes have an EXTRA copy of gene e.g XXY, while two other gametes LACK a required copy e.g XO
So, the right answer is some gametes may have an extra copy of some genes.
Good afternoon, Nicol3713. I think the answer would be B - Rough ER because the bound ribosomes are attached to the rough ER or nuclear envelope. It should be right. Let me know if you need any more help. Have a great day!!
Stem cells can specialize into any type of cell in the body
