  1. 8 hours ago · The cell is in a quiescent (inactive) stage, having exited the cell cycle. Some cells enter G 0 temporarily until an external signal triggers the onset of G 1 . Other cells that never or rarely divide, such as mature cardiac muscle and nerve cells, remain in G 0 permanently.

  2. 4 days ago · Cell cycle is the name we give the process through which cells replicate and make two new cells. Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA. So, S stands for DNA synthesis.

  3. 47 minutes ago · The cell cycle refers to the entire process by which a single cell grows and then divides into two daughter cells. It comprises four phases or stages: G1, S, G2, and M. During the G1 phase of the cycle, cells increase in size.

    1 day ago · Overview of chromatides' and chromosomes' distribution within the mitotic and meiotic cycle of a male human cell Meiosis occurs in all animals and plants. The result, the production of gametes with half the number of chromosomes as the parent cell, is the same, but the detailed process is different.

    3 days ago · Once activated, p53 will induce a cell cycle arrest to allow either repair and survival of the cell or apoptosis to discard the damaged cell. How p53 makes this choice is currently unknown. WAF1/CIP1 encodes for p21 and hundreds of other down-stream genes. p21 (WAF1) binds to the G1 - S / CDK ( CDK4 / CDK6 , CDK2 , and CDK1 ) complexes (molecules important for the G1/S transition in the cell cycle) inhibiting their activity.

  6. 1 day ago · The carbon reduction cycle is known as the Calvin cycle, but many scientists refer to it as the Calvin-Benson, Benson-Calvin, or even Calvin-Benson-Bassham (or CBB) Cycle. Nobel Prize –winning scientist Rudolph A. Marcus was later able to discover the function and significance of the electron transport chain.
