what is chromosome cycle, cytoplasmic cycle and centrosome cycle ?
Answers
Answer:
chromosome cycle :At the heart of the eukaryotic cell-division cycle are the precise duplication and segregation of chromosomal DNA. These two events take place at distinct points of the cell cycle: DNA is replicated during S phase, and then the replicated DNA strands are accurately partitioned to the two daughter cells during M phase
cytoplasmic cycle : With the right techniques, the final stage in the cell cycle, mitosis (M), can be observed using a good light microscope. Cytoplasmic division or Cytokinesis separates the original cell, its organelles and its contents into two more or less equal halves.
centrosome cycle : The centrosome cycle consists of four phases that are synchronized to the cell cycle. These include: centrosome duplication during the G1 phase and S Phase, centrosome maturation in the G2 phase, centrosome separation in the mitotic phase, and centrosome disorientation in the late mitotic phase—G1 phase.
Answer:
❐ Chromosome Cycle
At the heart of the eukaryotic cell-division cycle are the precise duplication and segregation of chromosomal DNA. These two events take place at distinct points of the cell cycle: DNA is replicated during S phase, and then the replicated DNA strands are accurately partitioned to the two daughter cells during M phase.
❐ Cytoplasmic Cycle
With the right techniques, the final stage in the cell cycle, mitosis (M), can be observed using a good light microscope. Cytoplasmic division or Cytokinesis separates the original cell, its organelles and its contents into two more or less equal halves.
❐ Centrosome Cycle
Centrosomes are the major microtubule organizing centers (MTOC) in mammalian cells. Failure of centrosome regulation can cause mistakes in chromosome segregation and is associated with aneuploidy.
