The answer was D..............I DID IT AND GOT IT RIGHT
Answer:
Option A, B, C, D and E
Explanation:
The first option indicates an early retroviral colonization of large double-stranded DNA viruses, which are the presumed ancestors of the eukaryotic nucleus; and then inappropriate activation of the telomerase can be implicated in the development of cancer by continous elongation of the telomere length without control.
Its activity can also be turned off leading to continuous shortening during replication and bringing about senesence and aging. the T-loops formed by the activity of the telomerase protects the ends of the chromosomes from being recognized as being broken and degradation.
Answer:
Pleiotropy
Explanation:
The single gene responsible for expressing many characters/traits is called pleiotropy. The sickle cell anemia disease is pleiotropic that is caused by HBB gene mutation. The mutation results in multiple traits (consequences) due to single gene mutation.
The RBCs shape changed to sickle shape this results in low energy levels, blood clots, and strokes. The mutation forms HbS (hemoglobin S) from hemoglobin beta globin subunits. Thus, this is an example of <u>Pleiotropy.</u>
Because bacteria are one of the smallest organisms as they are prokaryotes and are unicellular organisms with simple structure don’t take long to multiply because not many sub cellular structures are needed to be made (or divided through mitosis)
Answer:
I suppose the answer is C
