Explain its normal role and why scientists would regard it as the "guardian of the genome."

5 0

The gene p53, also called the guardian of the genome is located on the 17th chromosome in human genomes.
It was given this alternative name because it has a role in response to damage of DNA molecule and in preventing cancer.
The protein product of this gene stops the replication of damaged DNA, activates proteins that repair the DNA damage and if the reparation proteins fail to fix the damage it activates the process of apoptosis or so-called cell death in order to prevent the damaged cell to proliferate and potentially develop into a tumor.

Likurg_2 [28]

Answer:

Processing and storing food.

Explanation:

The coelom is the hollow structure formed in the organisms filled with the coelom fluid. The coelom is formed during embryogenesis which may be lined by the mesodermal layer or not.

The formation of coelom serves many functions in different organisms like it allows the internal movement of the organs in the body, allows the independent movement of the digestive tract, the fluid present in the cavity acts as a hydrostatic skeleton in the lower organism and cushions the internal organs.

The function that is not performed by the coelom is that it is not involved in the processing and storing food in organisms.

Thus, Processing and storing food is correct.

What is the differences between DNA virus and RNA virus

Rom4ik [11]

Answer:

They contain different genetic material.

Explanation:

DNA viruses contain DNA for genetic material while RNA viruses contain RNA. When RNA viruses enter a host cell, they must convert their RNA into DNA. DNA viruses change the biochemical functions in the nucleus for DNA replication and creates RNA that controls the proteins needed by the DNA virus (capsid).
