Apromoter sequence is likely to be (check all that apply):
a. located within a few dozens nucleotides of the gene it controls
b. orientation dependent
c. orientation independent
d. located downstream of the gene it controls
e. located upstream of the gene it controls
f. located either nearby or at great distance from the gene it controls

Option E.

Promoter sequence is located upstream of gene it controls.

Explanation:

Promoter sequence is a sequence of DNA that shows where transcription of a gene by RNA(ribonucleic acid) polymerase starts. It is located at the upstream of the gene or transcription start site of the gene it controls. It controls the binding of RNA polymerase to DNA(deoxy ribonucleic acid)

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

answer; both surfaces of the membrane are nonpermeable
