Chromosomes replicated

WebAdditionally, during mitosis, the replicated chromosomes are identical, while during meiosis the replicated chromosomes are homologous Protein synthesis is the process by which the genetic information contained within DNA is translated into proteins. This process begins with transcription, where DNA is transcribed into messenger RNA (mRNA). WebPrior to S-phase each chromosome is a single chromatin fiber. During S-phase the DNA is replicated and this results in two chromatin fibers (known as sister chromatids). However, these chromatin fibers are attached to each other at the centromere and together they make up a post S-phase chromosome.

WebChromosomes and cell division As a cell prepares to divide, it must make a copy of each of its chromosomes. The two copies of a chromosome are called sister chromatids. The … 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.

WebA diploid cell starts with 2N chromosomes and 2X DNA content.
