Answer:

<u><em>They take nutrients needed by healthy cells, and as they grow they interfere with the function of normal cells and organs.</em></u>

Explanation:

Many mutations can lead to the formation of cancer. Cancer can be described as an abnormal type of cell division of the cells of the body. As cancer cells are the cells of the body dividing abnormally, the immune cells fail to fight them. These cells keep on dividing and also disturb the functioning of the neighbouring cells and tissues. They even take up most of the nutrients required by normal body cells hence, being very toxic for the normal cells.

Two potential functions that eukaryotic cells perform to regulate transcription are
tester [92]
Two potential functions that eukaryotic cells perform to regulate transcription are DNA methylation: a process of epigenetics that participates in the regulation of the gene expression in two ways, directly impeding the union of the transcription factors, and indirectly propitiating the closed structure of the chromatin, and Histone acetylation, enzymes that acetylate conserved lysine residues in histones by transferring an acetyl group from an acetyl-CoA molecule, to form ε-N-acetyl lysine, is extensively associated with an open chromatin structure and therefore accessible to transcription factors, which increases gene expression.

Nady [450]

Ostrovityanka [42]

Answer:

1. 2 alleles, solid brown and spotted

2. 1 dominant, spotted, and one recessive, solid

3. Dominant: 16/24  Recessive: 8/24. Spotted- R, solid, r. There are 6 RR, 4 Rr and 2 rr.

4. It would slowly become more common and common. When a spotted and a solid pairs, its still most likely that the offspring will be spotted, however as most spotted die the number of spotted getting offsprings decrease.

5. No genetic variation, everyone in the population has that trait
