Question

QUESTION 4 a variable distance Eukaryotic genes (G) are regulated by promotors (P) and enhancers (E). On a given chromosome, the most likely order for these three elements is a. G...PE b. P...EG C. PE...G d. E...GP . E...PG QUESTION 5 The promoter of a gene a. is located right next to the gene b. determines whether or not mRNA is transcribed from the gene c. is the binding site for RNA polymerase d. is a controlling region for a gene o all of the above Click Save and Shrmit tone and submit.

Answer 1

Answer with explanation is given below :-

Question 4 .

Ans . e) E....PG

Explanation :-

DNA bending brstein Enhancer 11 ST 11 bromstor gene Pistom Promotor s are located near the trans- cription start sites of genes, Prohistor found a right next to where a gene is about to be transcribed on the other hand enhancer does not need to be located near the transcription start site some enhancer found located in several hundred thousand base pairs upstream or dousi stream of the initiation site. so, e) Er... PG is the correct answer

Question 5:

Ans . e) all of the above

Explanation :-

gene i promotor - am A promotor is located right next to the gene. . (right upstream). .. . RNA polymerase binds to the DNA of the gine at a specific region known as Pronstor . to initiate transcription Process As Promotor is a nital component of expression vectors they con control the RNA polymerase binding as well as gene. Because mRNA transcribes from DNA by RNA polymerase and ultimately mRNA translated into a functional protein promotor also con determines wheather or not mRNA is transcribed from the gene r e) all of the above is the correct answer i
