How many divisions happen in mitosis? How many chromosomes does the cell have in the G1 stage of the cell cycle? If a eukaryotic cell has 20 chromosomes and it undergoes meiosis, how many cells will result and how many chromosomes will they contain? a. 4 cells, each with 20 chromosomes...
How many cells constitute the body of an adult? What is the sperm stem cells? What happens in a cell during the S portion of interphase? What is sexual reproduction? What is the function of RNA and DNA in mitosis? Describe how internal reproducti...
Megakaryocytes grow so large because the DNA within the cell duplicates many times — but without the cell undergoing cell division: a process called endomitosis. A megakaryoblastic can shelter more than 120 sets of nuclear DNA before it eventually becomes the biological equivalent of a supernova...
Such a cell cycle is divided in four phases: (i) Initiation: stressed tumor cells undergo catastrophic mitosis or cell death. Surviving cells assume a tetraploid or polyploid transient state [1,11]; (ii) Auto-renovation: tetraploid cells start endocycling to produce mononuclear or multinuclear ...
