Which stages make up interphase of the cell cycle?
Interphase{G1 (cell growth), S (DNA is copied), G2 (growth and preparation for cell division)}, Cell Division {mitosis and cytokinesis} False
What 2 processes make water cycle?
Evaporation , condensation makes water cycle. These are reversible processes.
Are photosynthesis and cellular respiration the two main processes that make up the nitrogen cycle?
carbon cycle
What is the overall goal of the cell cycle?
An important function of many checkpoints is to assess DNA damage, which is detected by sensor mechanisms. When damage is found, the checkpoint uses a signal mechanism either to stall the cell cycle until repairs are made or, if repairs cannot be made, to target the cell for destruction via apoptosis (effectormechanism). All the checkpoints that assess DNA damage appear to utilize the same sensor-signal-effector mechanism.The cell cycle, according to Temple and Raff (1986),[ 1] was expected to function as a clock; but, if this were the case, it would be expected that the stages of the cell cycle must function according to some sort of internal clock, which would determine how long a phase should last. However, the cell cycle is now depicted as falling dominoes: The preceding phase has to "fall" before the next phase can begin. The cell cycle checkpoints are, therefore, made up of composites of protein kinases and adaptor proteinsthat all play salient roles in the maintenance of the cell division's integrity.The DNA damage checkpoint is always active. Nonetheless, most human cells, for example, are terminally differentiated and must exit the cell cycle. There is a phase late in G1 phase called the restriction point (RP, or the restriction checkpoint); cells that should cease division exit the cell cycle and enter G0. Cells that continually divide in the adult human include hematopoietic stem cells and gut epithelial cells. Therefore, the re-entrant into the cell cycle is possible only by overcoming the RP. This is achieved by growth factor-induced expression of cyclin D proteins. These then overcome the G0 barrier and are able to enter the cell cycle.
The process of is similar to what happens in nature in the water cycle?
Four processes make the water cycle. These are evaporation, condensation, precipitation and collection.
What two processes make up the m phase of the cell?
Mitosis And Cytokinesis
Which stages make up interphase of the cell cycle?
Interphase{G1 (cell growth), S (DNA is copied), G2 (growth and preparation for cell division)}, Cell Division {mitosis and cytokinesis} False
What 2 processes make water cycle?
Evaporation , condensation makes water cycle. These are reversible processes.
The sequence of growth and division of a cell make up the?
Cell Cycle
Does a cell make a copy of its DNA during the stage of the cell cycle called mitosis?
No. Mitosis is strictly the stage of the cell cycle where the chromatin condenses into chromosomes, the nuclear envelope dissolves, the chromosomes line up on the metaphase plate, spindly fibers attach to the kinetochores of each chromosome and "pull" sister chromatids apart to opposite poles of the cell. Then the cell pinches off and forms a nuclear envelope around the DNA. The stage in the cell cycle where a cell duplicates its genetic material is called the S phase, preceded by the G1 phase, followed by the G2 phase, then mitosis and cytokinesis.
What are the 7 stages in the cell cycle?
The 7 stages for somatic cells (non-sex cells) are the G1 phase, S phase, G2 phase (these make up interphase) and then prophase, metaphase, anaphase, telophase (these are mitosis).
When does a cell copy its DNA?
The chromosomes are replicated so they are able to be split into daughter cells through the cell cycle.
Which processes make up the water cycle and how are they connected?
The processes evaporation , condensation, precipitation and collection make water cycle. They are connected to each other, change of state of water occurs.
Are photosynthesis and cellular respiration the two main processes that make up the nitrogen cycle?
carbon cycle
What would happens To a cell and it's offspring if the cells did not go through a G1 phase during their cell cycle?
If cytokinesis did not occur in the cell cycle, the resulting product would be one cell with two nuclei and 2 sets of DNA and other organelles. What would most likely happen is the cell would under go Apoptosis, or programmed cell death.
What are the four stage of the cell cycle?
G1 Phase (resting phase, also the longest), S phase (synthesis of DNA), G2 phase (cell syntheszes proteins needed for chromosome sorting and cell division), M phase (Mitosis- process of making 2 daughter cells and Cytokinesis - process of dividing the cytoplasm to produce 2 daughter cells.)
How does a duplicated chromosome differ from a chromatid?
Chromosomes are what make up your genetic material. During interphase when the chromosomes are duplicating, they remain attached to their duplicated with a centromere. When they are connected with their duplicate, each individual of this pair is called a chromatid. So a duplicated chromosome is made up of two chromatids which are identical to each other.
