Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. Apart from this reduction in chromosome number, meiosis differs from mitosis in yet another way. Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells.
You could cover the sand dunes with tarps that are attached into the ground with stakes, or routinely spray them with lots of water to make the sand heavier and less likely to be picked up by wind.
Answer:
D. The site of transcription is within the nucleus
Explanation:
this is because the process of DNA is converted into RNA
This requires a protein called RNA polymerase. It will copy certain regions of DNA and convert them into RNA (this occurs in the nucleus) and then this RNA goes to the cytoplasm, where it will be translated into a protein.
Therefore, its D.
Answer:
Outcome of irregular mitosis:
Mitosis may be defined as the process of cell division in which a single diploid parent cell divides to form two diploid daughter cells. The irregular mitosis may result in aneuploidy condition of chromosome in which the the extra (trisomy) or missing (nullisomy) of one or more chromosome may occur. This condition also leads the genetic disease and cancer condition. Non disjunction may occur in which the sister chromatid are unable to separate.
Outcome of irregular meiosis I and meiosis II.
Meiosis is the cell division in which a single diploid parent cell divides into four haploid daughter cells. Nondisjunction at meiosis I prevent the segregation at least one homologous chromosomes. This causes the two cells with extra copy of chromosome and two cells with deleted chromosome. Nondisjunction at meiosis II. Two cells have normal chromosomes and two cells with the abnormal (missing and extra) chromosomes.
