Answer:

In p53 pathways, 3 proteins which are mutate and cause cancer that proteins are:

1.BRCA2  

2. p53 in Rb genes binds with deoxyribonucleic acid that stimulates another gene to produce a protein known as p21 that interacts with cdk2. When p21 is combined with cdk2  cell will not pass through to the next stage of cell division. This is Li-Fraumeni syndrome (when p53 causes cancer from parents to offspring)  

3.BRCA1  

The parent that transmits mutation in one of these genes has a 50% chance of inheriting the mutation. The effects of mutations in BRCA2 and BRCA1 are seen when the person's second copy of the gene is normal.

A cross country runner runs 8 km in 2 minutes. What is his speed?
oee [108]

The speed of the cross country runner is equal to 4 km/min.

<u>Given the following data:</u>

  • Distance = 8 km.
  • Time = 2 minutes.

To determine the speed of the cross country runner:

Speed can be defined as the distance covered by an individual per unit time and it can be measured in kilometer per minutes (km/min).

Mathematically, speed is given by the formula;

Speed = \frac{distance}{time}

Substituting the given parameters into the formula, we have;

Speed = \frac{8}{2}

Speed = 4 km/min.
