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.

Maurinko [17]

Answer:

El cuadro no está presente pero las diferencias principales entre células eucariotas y procariotas son:

Eucariotas:

Tienen núcleo

Tienen organelas

Tienen Vacuolas

Tienen Citoesqueleto

Tienen Cloroplastos

El ADN está asociado a proteínas

El ADN es lineal

Presentan mitocondrias

Presentan un sistema de endomembranas

Procariotas:

No tienen núcleo

No tienen vacuolas

No tienen cloroplastos

No tienen organelas

El ADN no está asociado a proteínas

El ADN es circular

Presenta mesosomas

Explanation:

Las células procariotas son más primitivas que las eucariotas, por ende, sus estructuras son más simples. Las células procariotas están en organismos unicelulares tales como las bacterias, mientras que las células eucariotas están en organismos unicelulares y pluricelulares como en plantas, animales, u hongos. La diferencia más notoria entre ambos tipos de células es la ausencia de núcleo en las procariotas haciendo que el ADN está disperso en el citoplasma mientras que en las células eucariotas, el ADN está dentro del núcleo celular.
