Answer:
B) Telomerase is a ribonuclear protein containing a section of RNA complementary to the telomeres
C. telomerase is reactivated in cancer cells, contributing to their immortality
Explanation:
- Telomerase elongates telomere ends
- Telomerase binds to a RNA molecule containing a sequence complementary to the telomeric repeat.
- Telomerase is usually not active in somatic cells but is active in cancer cells- the protein acts to extend the shortened telomeres in these cells preventing them from dying
Answer:
its the second one because genetic engineering is somelike fake
Answer:
The scheme of the tautomers of cytosine, guanine and thymine are found in the attached file
Explanation:
The primary imine-amine tautomerism occurs in heterocyclic compounds where hydrogen may be forming the amino group (primary amine form) or migrate to adjacent nitrogen (imine form), may occur in some nitrogenous bases such as cytosine. Thymine shows double lactam-lactymal tautomy (where hydrogen migrates from the nitrogen atom to the oxygen atom of the heterocycle oxo group (lactam form) and vice versa (lactose form)), and guanine and cytosine can both.
In my opinion sure industries be able to pay scientists to perform
