Answer:
p53 gene is an important gene that regulates the proper functioning of the cell. This gene plays an important role in the cell cycle progression and acts as genome guardian.
Any mutation in p53 leads to the formation of the different types of cancer cells. The p53 gene is activated by teh phosphorylation at the particular sites. High levels of phosphorylated p53 in the cell indicates that the cells DNA is highly damaged and mutated.
Answer:
Both mitosis and meiosis are processes of cell division. They use the same steps for cell division, including prophase, metaphase, anaphase and telophase.
Differences between mitosis and meiosis:
Mitosis is the process of asexual reproduction, while meiosis involves sexual reproduction. Higher life forms, such human beings and animals undergo meiosis. The resulting offspring is genetically different in the case of meiosis, while the offspring is identical in the case of mitosis. Meiosis includes two steps of division, compared to the single step of mitosis. During the process of meiosis, the number of chromosomes is reduced by half, while in mitosis, they remain the same. Also, mitosis produces 2 diploid cells, while meiosis produces 4 haploid cells.
