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.

Uncovering the secrets of how chromosomes assemble
WebIn a regular somatic cell (before DNA is replicated in the S phase), there are 46 chromosomes - 23 of each kind as well as their homologous opposite. I.e. - you have an 'A' chromosome (1 'A' chromatid) and an 'a' chromosome (1 'a' chromatid), 'B' and 'b', … WebIn preparation for cell division, DNA is replicated, and the replicated DNA is packaged into an X-shaped chromosome. This process is ... loading and chromosome assembly, and gathered evidence that WebOct 27, 2024 · Upon recombination, a pair of chromosomes is referred to as a tetrad. In mitosis, crossing over does not occur and the resulting replicated chromosome pairs are just that, chromosome pairs. So the tetrad refers solely to a pair of recombined chromosomes during meiosis.
