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.
Answer: the answer is choice b
Explanation: based on knowledge about food chains, this choice makes the most sense
Hope this helps, and please give brainliest!
I’m pretty sure the answer is A because carbon dioxide causes a solution to turn yellow and a solution that indicates no carbon dioxide would be blue instead of green.
The disorder allele is recessive
