Answer: First, p53 triggers production of Cdk inhibitor proteins, pausing the cell cycle in G1 to allow time for repairs. ... In cancer cells, p53 is often missing, nonfunctional, or less active than normal. For example, many cancerous tumors have a mutant form of p53 that can no longer bind DNA.

Explanation:

atpase pump can also be called atp synthase. this enzyme catalyses atp formation from adenosine diphosphate and phosphate. it has f1, stalk and f0 components. 3 positive hydrogen ions go through to make 1 adenosine triphosphate molecule. oxidative phosphorylation has to do with the loss of electrons. there would be electrons loss from NADH to FADH2. Cytochromes carries them through different series of transferases from I to IV and while on this positive hydrogen ions are released into mitochondrial matrix

positive hydrogen ions are moved back to lumen through adenosine triphosphate channels. a process called chemiosmosis. the pro

Determine the proportion of offspring phenotypes that would result when two merle dogs mate, if both dogs are heterozygous (Ll)
Brut [27]

Answer:

75% would have the dominant traits for coat length, 25% would have recessive trait for coat length.

Explanation:

After completing a punnet square, we could find that our genotypes are 25% LL, 50% Ll, and 25% ll.

If these genotypes were to be physically expressed, LL and Ll would both be expressed as showing the dominant trait.

This means that 75% would have the dominant traits for coat length and 25% would have recessive trait for coat length.

I hope this was helpful! Let me know if you need any clarity.
