Elephants have multiple copies of the p53 genes that play an important role in the control of cell division.
<h3>What is the role of p53 genes in elephants?</h3>
P53 is an important regulator of the DNA repair processes and controls uncontrolled cell proliferation. When DNA is harmed, the protein becomes active and aids in orchestrating a response that stops DNA replication and fixes any incorrect copies of the cell. The oncogene MDM2 E3 ubiquitin ligase, another protein, is responsible for deactivating the p53 repair activity in duplicated cells with intact DNA since it is not required.
A human with only two alleles from a single gene has much fewer molecular anti-cancer interactions than an elephant, which has 40 alleles, or versions, from its twenty p53 genes. Although the elephant may appear to have excessive genetic diversity, each of its 40 alleles is structurally slightly different.
I understand the question you are looking for is this:
Compared to humans, elephants have a dramatically low instance of cancer. Elephants have multiple copies of the _____ genes that play an important role in the control of cell division.

Answer:
Companion cell is a type of specialized parenchyma cell, which is located in the phloem of the flowering plants.
Each of the companion cell is usually associated with the sieve element. The main function of the companion cell is uncertain but it regulates the activity of sieve tube.
It plays a major role in the loading and unloading of the sugar molecules into the sieve element. As the sieve tubes do not have nucleus and ribosomes so they need companion cell to help in the transportation of sugar molecules.
Answer: The introduction of a plant variety The introduction of a plant variety
that is resistant to insect pests.
Explanation:Gene flow can simply be said to be gene movement from one population to another population.
Gene flow can also mean the movement of the pollen across from one population of white spruce to another. It can be in the form of introduction.
The process of osmosis explains what happened to the cells.
Osmosis is where water molecules will flow from a region of higher water potential to a region of lower water potential, through a partially permeable membrane. Red blood cell is a human cell and have a partially permeable membrane. At the same time, pure water has the highest water potential among all substances, and of course higher than the cytoplasm of the red blood cell, therefore, water molecules will flow from the water to the red blood cell.
So much water has flown to the red blood cells that the cell membrane cannot hold all and eventually the cell bursts. Therefore, the process of osmosis explains this result.
