A cell has 36 chromosomes. After it divides by mitosis, how many chromosomes will be in each cell?
butalik [34]

Answer:

36 chromosomes in each cell

Explanation:

Mitosis is an equational division which means that it does not reduce or change the number of chromosomes in the daughter cells. Mitosis in a single parent cell produces two daughter cells each having the same DNA content and the number of chromosomes is present in the parent cell. Each chromosome after the S phase has two sister chromatids that separate from each other and are segregated to the opposite poles of the cell during anaphase of mitosis. Therefore, a cell with 36 chromosomes will form two daughter cells after one round of mitosis. Each daughter cell would have 36 chromosomes.

Why are red blood cells unable to replace damaged proteins
Rainbow [258]

The sole reason why red blood cells are unable to replace damaged proteins is that red blood cells lack DNA and cell organelles such as the nucleus, ribosomes, and mitochondria which are crucial for protein synthesis, assembly, and repair. In other words, they lack both the information and the machinery for making or repair of proteins.

Due to lack of DNA and cell organelles, red blood cells cannot be able to satisfy the central dogma which summarizes synthesis of proteins as DNA → RNA → proteins.

DNA has the genetic information on how proteins should be made, RNA is responsible for transferring the information from DNA in the cell nucleus to the ribosomes in the cytoplasm,  then translating or decoding this information, which results in the making of protein.
