MRNA strand: TATACGA
Shtirlitz [24]

Answer:

The  mRNA strand for TATACGA is UTUTGCT.

Explanation:

The DNA bases are adenine (A), thymine (T), guanine (G), and cytosine (C). Each of these bases pairs with a complimentary one. Adenine pairs with thymine, and cytosine pairs with guanine.

During transcription, the DNA is transcribed into an mRNA strand. The mRNA has the same complementary bases of the DNA strand, with the difference that instead of having adenine base the complementary base of thymine, it has uracil (U). When we interpret the DNA strand TATACGA, the mRNA will be adenine (A) paired with the DNA's thymine (T), uracil (U) paired with the DNA's adenine (A). Then the same sequence repeats itself. After that, guanine (G) pairs with DNA's cytosine (C), cytosine (C)pairs with the DNA's guanine (G), and lastly, thymine (T) with the DNA's adenine (A).

What roles does estrogen play in the feedback mechanism?
Mademuasel [1]
"Estrogen is involved in a feedback mechanism associated with the follicular phase of menstruation.<span> In a negative feedback mechanism, estrogen released from follicles influences the pituitary gland to decrease the production of follicle stimulating hormone, also known as FSH. In a positive feedback mechanism, rising estrogen causes FSH to increase"
