S phase is especially important as this is the point at which the cell’s entire genome is duplicated through the process of semi-conservative DNA replication. The stages of mitosis vs. meiosis The stages of mitosis are interphase, prophase, metaphase, anaphase and telophase, sometimes followed ...
Diagram summarising the centromere number of anther cells at different early meiosis stages.Ruoyu, WenGraham, MoorePeter, J. Shaw
Telophase is a late stage in mitosis and meiosis, two types of cell division in eukaryotes. During telophase, the two new daughter cells form nuclear membranes that separate the DNA from the cytoplasm. In eukaryotes, DNA is enclosed by the nucleus to keep it separate from the rest of the ...
They alternate, or change back and forth, each generation, between two different stages of life. Each generation of the plant will look, not like its parent plant, but like its grandparent. Plants alternate from a diploid stage, called a sporophyte, to a haploid stage, called a gametophyte...

Meiosis, division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each with half the number of chromosomes of the original cell. The process of meiosis is characteristic of organisms that reproduce sexu
centromere and chromatids in cell divisionDuring the first stages of cell division, the recognizable double-stranded chromosome is formed by two tightly coiled DNA strands (chromatids) joined at a point called the centromere. During the middle stage of cell division, the centromere duplicates, and...

What is the life cycle of moss? There are two stages that mosses go through in their life cycle. The first stage is haploid (gametophyte) and the second stage is diploid (sporophyte), change is known as the alternation of generations. This unique reproductive cycle starts when two male and...
