.A researcher alters the DNA-binding domain of a glucocorticoid receptor to that of an estrogen receptor. How would the cells re
spond to exposure to glucocorticoids?a. They would bind estrogen, and initiate estrogen-dependent synthesisb. They would bind glucocorticoids, and initiate testosterone-dependent synthesisc. They would bind estrogen, and initiate testosterone-dependent synthesisd. They would bind glucocorticoids, and initiate estrogen-dependent synthesise. They would bind neither hormone
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.
The best way to classify two different organisms that have similar appearance and are found in the same environment is to use gel-electrophoresis to compare DNA patterns.
Explanation:
When organism possesses the same physical characteristics and are found in the same environment the genetic test must be varried out to ascertain their differences such as DNA test using electrophoresis to compare such
