When DNA is wrapped around histones, the genes cannot be transcribed into RNA (and, eventually in protein). So these enzymes come along called HATs, which chemically modify the histones in effect loosening their grip on the DNA. read file into buffer c++ https://triplebengineering.com

WebThe two gametes (sperm and ovum) contain 23 chromosomes (n) each and when the sperm fertilizes the egg (ovum), the zygote now has a total of 46 chromosomes and becomes diploid (2n). This zygote then goes through many stages of the replication cycle to create more and more cells called somatic cells or body cells. WebDuring telophase, chromosomes arrive at opposite poles and unwind (uncoil) into thin strands of DNA, the spindle fibers disappear, and the nuclear membrane reappears. Cytokinesis is the actual splitting of the cell membrane, which takes place by furrow formation in animal cell while plant cells form a cell plate that becomes the new cell wall.
