Each time a chromosome is replicated

WebAug 15, 2024 · Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of … WebAny accidental changes in chromosome structure will be permanent. These changes will be passed on through future rounds of DNA replication. Therefore any loss of DNA is a serious problem. If the end of a DNA strand is not copied each time the DNA is replicated then the chromosome will shrink continuously as the cell cycle continues.

WebThe ends of these chromosomes cannot be fully copied during replication, resulting in a slow, gradual shortening of the chromosome over subsequent replication cycles; this is known as the end-replication problem. This is … WebThis is what it enters into. But if the cell checks it and it says you're big enough you're ready to replicate. It goes onto the S. Phase and this is the DNA replication phase. And so the sister chroma tides are made here because they are the copy of the same chromosome. So you have a chromosome here and it gets replicated. dracula theme gms2 https://sptcpa.com
