Answer:
d) They would bind glucocorticoids, and initiate estrogen-dependent synthesis
Explanation:
Both Glucocorticoids and estrogens Hormones have important but distinct physiologic functions. These two hormones belongs to the two classes of steroid hormones. Both of these hormones binds to their specific receptors.
DNA binding domain is the domain that after activation by external factors such as hormones express the specific proteins by binding to specific region of the DNA.
As DNA binding domain of a glucocorticoid receptor is altered with DNA binding domain of estrogen receptor so it means binding site of the glucocorticoid hormone for glucocorticoid receptor remains the same and binds to glucocorticoids but on binding it activates the estrogen DNA binding domain which further binds to specific region in the DNA which initiates estrogen dependent synthesis.
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:
The Canals made shipping more efficient, but as an unintended consequence also allowed rapid expansion of the zebra mussel's range. By the 1830s, these mussels covered much of Europe and Britain.
Successful introduction of zebra mussels into the Great Lakes probably occurred in 1985 or 1986, after transoceanic ships discharged contaminated ballast water from foreign ports into lakes St. Clair and
The correct answer is:
C. All cells come from other cells
Explanation:
The generally believed parts of modern cell theory insert: All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and purpose in all living organisms.
