WebApr 9, 2024 · Chromosome and DNA Replication When the cell enters S-phase in the cell cycle (G1-S-G2-M) all the chromosomal DNA is replicated. This is done by enzymes called DNA polymerases. All DNA polymerases synthesize new strands by adding nucleotides to the 3'OH group present on the previous nucleotide. Webcycle," says Tatsuya Hirano of the RIKEN Chromosome Dynamics Laboratory.

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. five decaying nightsWebthe period of the cell cycle at which the duplicated chromosomes are separated into identical nuclei; includes prophase, prometaphase, metaphase, anaphase, and telophase mitotic phase the period of the cell cycle when duplicated chromosomes are distributed into two nuclei and the cytoplasmic contents are divided; includes mitosis and cytokinesis five decathlon
