If a cell has completed meiosis I and the first cytokinesis, and is just beginning meiosis II, which of the following is an appropriate description of its genetic contents?

Respuesta :

The appropriate description of the genetic content of a cell that just completed meiosis I and cytokinesis and is about to begin meiosis II is that: it has half the amount of DNA as the cell that began meiosis

MEIOSIS:

  • Meiosis is the cell division that results in daughter cells with a reduced number of chromosomes (by half). It occurs in two distinct stages; Meiosis I and Meiosis II.

  • Prior to undergoing any cell division including meiosis, the cell undergoes a phase called Interphase where it replicates its genetic material (DNA).

  • The genetic material (DNA) content duplicates i.e. × 2 of the original number, during this phase. Each chromosome duplicates to form sister chromatids joined at the centromere

  • In meiosis I, homologous chromosomes (similar but non-identical chromosomes received from each parent) separates.

  • Hence, the actual reduction in chromosomal number occurs in meiosis I, which also affects the DNA content, as each divided cell i.e. after cytokinensis, now contains ½ of the DNA that started the actual meiotic division.

  • Therefore, after meiosis I and first cytokinesis, a cell will contain half the amount of DNA as the cell that began meiosis.
