Proto‑oncogenes are genes that have the potential to become oncogenes through either mutation or an increase in expression. Clas
algol [13]

Answer:

<u>Proto-oncogenes</u>

  • These genes code for protein that normally promote cell division
  • Mutations that increase activity of these genes may lead to cancer

<u>Tumor suppressor genes</u>

  • These genes code for protein that normally prevent uncontrolled cell division
  • Some products of these genes normally function in repairing damaged DNA
  • Mutation that decrease activity of these genes may lead to cancer.

Explanation:

<em>Proto-oncogenes</em> are group of genes that ordinarily help cells develop. At the point when a proto-oncogene mutates or there are such a large number of duplicates of it, it turns into a "terrible" quality that can turn out to be forever turned on or activated when it shouldn't be. At the point when this occurs, the cell becomes wild, which can prompt malignant growth. This terrible quality is called an oncogene.

Tumor suppressor genes are normal gene that hinder cell division, fix DNA missteps, or tell cell when to undergo apoptosis (die). At the point when tumor suppressor gene don't work appropriately or inactivated, cells can develop uncontrollable growth, that ultimately lead to cancer.

MariettaO [177]

Answer:

Organism D.

Explanation:

Amino acids are the monomers of proteins and are linked together by the peptide bond. The protein is obtained from the RNA molecules by the process known as translation.

The amino acid sequence of the proteins can also be used to study the evolutionary relationship between the organisms and the closeness of teh organisms with each other. In the question it is give that organisms A and D has least difference ( 1 amino acid sequence difference) and more related with each other.

Thus, the answer is organism D.

HELP ME. What are ways that ordinary people can help to keep antibiotic resistance from getting worse? Express your opinion abou
ycow [4]
By taking daily antibiotics, people are encouraging resistance by getting their immune systems used to the formulas. Antibiotic resistance<span> occurs when bacteria change in a way that reduces the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply, causing more harm. I think that people can help by not taking antibiotics for every little pain they have, instead try other simple remedies and only use medicines in cases where other remedies won't help. </span>
