Another difference between the stages of mitosis and meiosis is that in meiosis, homologous chromosomes pair up during metaphase instead of chromatids. In a homologous pair, one chromosome comes from the mother, and one chromosome comes from the father. Homologous chromosomes are very similar, but...

The chromosomes condense into tight bundles, and the nuclear envelope breaks down. The nucleolus also disappears. Spindle fibers form and attach to the chromosomes. What happens during prometaphase: Spindle fibers elongate and begin to overlap at either end of the cell. These regions are called po...

How many chromosomes are present when meiosis I starts? Somatic cells of the fruit fly have 8 chromosomes. What is the 2N number of chromosomes? How many chromosomes are contained within a human cell? How many chromosomes are there during metaphase?
At the onset of metaphase in mitosis, the 46 chromosomes are more or less lined up with one another, with their centromeres forming a fairly straight line from the top of the cell to the bottom (taking the positions of the centrosomes to be the left and right sides). "More or less"...
Genomic regions that appear as gaps or breaks on metaphase chromosomes when DNA replication is partially inhibited. ALT-associated PML bodies (APBs). Promyelocytic leukaemia (PML) bodies are dynamic protein aggregates within the nuclei of some cells that contain the PML protein. Alternative lengthening...
The first stage in the formation is prophase I, whereas metaphase II marks the second stage. During both stages, the nuclear membrane breaks down to provide access for spindle fibers coming from opposite cell poles. This way, all 46 chromosomes are pulled toward two separate poles to become ha...
