As the most junior member of a lab, you are tasked with generating cell lines that accumulate DNA damage to investigate how random mutations affect transformation of cells into cancer cells. You decide to mutate proteins in the p53 pathway. Which three proteins would you mutate

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 family is relocating from St. Louis, Missouri, to California. Due to an increasing inventory of houses in St. Louis, it is taking longer than before to sell a house. The wife is concerned and wants to know when it is optimal to put their house on the market. Her realtor friend informs them that the last 21 houses that sold in their neighborhood took an average time of 60 days to sell. The realtor also tells them that based on her prior experience, the population standard deviation is 14 days.

She could perform several wildlife surveys over time to observe any changes in the number and type of marine organisms in the ecosystem. B. She could add a chemical to the water to react with the waste products that the manufacturing plant is dumping into the marine ecosystem. C. She could ask the manufacturing plant to treat all of the waste products that they are dumping into the marine ecosystem. D. She could collect data on the amount of product made by the manufacturing plant and how much the product sells for in local cities.

which of the following hypotheses can be tested with experiments? select all that apply

1.) a diet low in sugar reduces the risk for heart disease
2.) coffee increases subject performance on intelligence tests
3.) people that brush their teeth live longer than those who don't brush their teeth
4.) scientists will find a cure for cancer before the year 2020

I know that 4 isn't the answer so I selected the other three and it said I was wrong. isn't a hypotheses something that can be experimented on so can't all of the three have experiments If I'm making sense ​

Fat cells are expandable. How does this structure relate to a fat cell's function?

A) Fat cells store energy for the body to use later, so being
