Hello!
You have three checkpoints here. One at the end of G1, one at the end of G2, and one in the middle of the Mitotic stage.
Let's go through these individually.
The G1 checkpoint determines whether or not a cell should begin cell replication. It checks to see whether the cell has grown to an appropriate stage. This checkpoint is seen as the most important. Therefore, this matches with "checks for cell size and DNA damage".
The G2 checkpoint determines if a cell is ready for mitosis. This checkpoint checks whether or not replicated DNA is correct. Therefore, this one matches with "checks whether DNA has doubled and repairs it if damaged".
The M checkpoint occurs at the end of metaphase. This makes sure the chromosomes have aligned properly at the metaphase plate and makes sure the sister chromatids are correctly attached to the spindle microtubules. Therefore, this one corresponds with "checks whether the microtubules have attached to the centromeres of the chromosomes".
Hope this helps!
2 diploid cells that are genetically identical to the parent cells
They have to use Restriction enzymes that would be used to cut the DNA into smaller pieces.
I hope this helped please give me brainliest
In 1885 Virchow said that all cells exist from pre-existing cells
Answer:
A. <u>Biomes are not affected by climate</u>
Explanation:
-
The climate of a biome determines its importance as the biomes are formed as a cause and consequence of the climatic factors and hence the plant growth is affected by this and depends on the climatic types hence the Koppen classification is based on the different climatic zones the relationship among the plantains.
- An example of the Mediterranean climate i.e Cs chappal biome. Has and extremely dry summers and plants are adapted to the extreme season of the variation in the temperatures and the rainfall patterns.
