So, as you know, when a sperm cells (Male sex cell) meets the Egg cell (Female Sex Cell) it forms something called a zygote. And from that point on, the egg cell reproduces more and more (making more cells) in a type of cell called a stem cell, which can be used for anything the body needs. The newborn babies keep these cells up until birth or the incubation (growth of the baby in the mother's uterus), and then they are ready to be born.
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.
