During which phase of meiosis does the nuclear membrane reform around the chromosomes?
Nuclear membrane forms around each group of duplicated chromosomes, the cytoplasm divides, and two daughter cells form. Sister chromatids remain together.
Humans have a life cycle that requires two types of cell division: meiosis and mitosis. When a sperm fertilizes an egg, the resulting cell is called a zygote, which is haploid in chromosome number. Because of meiosis, each body cell is genetically identical; they all have the same number and kinds of chromosomes.
Quiz over the basics of meiosis. Focuses on the stages of meiosis, number of chromosomes, and how the process is used to form gametes, like the sperm and egg.
21 paź 2023 · In biology, meiosis is the process where a cell replicates DNA once but divides twice, producing four cells that have half the genetic information of the original cell. It is how organisms produce gametes or sex cells, which are eggs in females and sperm in males.
Meiosis is the nuclear division that forms haploid cells from diploid cells, and it employs many of the same cellular mechanisms as mitosis. However, as you have learned, mitosis produces daughter cells whose nuclei are genetically identical to the original parent nucleus.
