Answer:
B)Cyclins regulate the timing of cell cycle
Answer:
Convergent Evolution.
Explanation:
When two different species that are very distantly related but have similar traits its Convergent Evolution due to environmental pressures.
Answer:True
Explanation:Basically thymine diamers are mismatched pairs (thymine binds with another thymine instead of binding with adenine) and may lead to unwanted results so the mismatching can be repaired by using two methods which are as follows :
1-the PRE enzyme activated by blue light breaks the thymine diamer and some of the surrounding bonds the strand is cut and DNA polymerase then restores the normal base pairing
2-UVR system breaks dimer creating a gap when a gap is created and the molecules appear unpaired it is filled by proof readers hence restoring normal base pairing.
Answer:
Glycolysis takes place in the cytosol which is part of the cytoplasm of the cell. Glucose is rearranged and phosphorylated to form F-1,6BP(fructose 16 bisphosphate which is very unstable) its splits into 2 phosphorylated 3C sugars (DHAP and G3P)(can interconvert) both form G3P to enter 3rd phase, G3P converted into pyruvate creates 4 ATP in total but has a net of 2 ATP and creates NADH. The raw materials needed are two molecules of NAD+ per glucose as well as 2 ATPs. Hope this helps!
