Nimfa-mama [501]

Answer:

CHK2, p53, p21, cell cycle progression.

In a normal cell with no LFS mutation, during the G1 stage of cell cycle progression, the CHK2 activates if there is damage in the DNA. CHK2 activates p53, which is a tumor suppressor protein that will hold the cell cycle in G1/S until the DNA is repaired. The p53 protein activates p21, a protein that binds to CDK2 and stops the cell cycle. The cell cycle will continue once the damage is repaired.

Nezavi [6.7K]

Meiosis is involved in the formation of the gametes of multicellular organisms.

<h3>How do multicellular organisms reproduce?</h3>

Both plants and animals reproduce by developing new individuals, through gametes or reproductive cells.

<h3>Characteristics of multicellular organisms reproduction</h3>

  • Many multicellular organisms always arise from a single cell called a zygote, the result of the union of two gametes (female and male).

  • The zygote subdivides rapidly throughout gestation, forming the entire body of the creature that, from its birth, begins to grow.

Therefore, multicellular organisms reproduce by means of certain types of reproductive cells that are generated and take care of building a complete new individual.
