Answer:
CHK2, p53, p21, cell cycle progression.
Explanation:
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.
It increases ecosystem productivity, protects fresh water resources, and provides nutrient storage and recycling
The main function of the smooth ER is to make hormones and lipids.
Answer: Arenite
Explanation:
Arenite can be defined as the sedimentary clastic rock.
It is of the sand grain size.
It also comprises of matrix.
It is a metamorphosed sediment.
Arenite is formed by the erosion of the turbiditic re-deposition of the sands. It belongs to silicatic limestones.
Answer:
The meaningful differences between organisms in a population are genetic. Variations in the genome of members of a population arise through mutation. Occasionally, a mutation occurs in an individual that is beneficial, that helps that organism be better able to survive and repoduce in its current environment.
