What Happens at the S-Phase of Interphase? - Seattle PI
WebApr 9, 2024 · 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. For this reason they are said to work in a 5' to 3' direction. WebS - each chromosome replicates to produce 2 daughter copies (sister chromatids) G2 - further replication of membranes, microtubules, mitochondria and other organelles. … WebChromosomes condense and become visible by light microscopy as eukaryotic cells enter mitosis or meiosis. During interphase (G1 + S + G2), chromosomes are fully or partially decondensed, in the form of chromatin, which consists of DNA wound around histone proteins (nucleosomes). In G1, each chromosome is a single chromatid. spotted ibstock facebook
