Compare and contrast two mechanisms for transcriptional termination in bacteria.
(rho)p-dependent termination: requires rut (rho utilization site), rho protein binds, moves towards 3' end, DNA encodes GC rich for stem loop, RNApoly pauses, rho protein catches up and separates RNA-DNA hybrid
(rho)p-independent termination: Uracil-rich sequence causes RNApoly to pause, stabilized by NusA near open complex RNA exit, UA bonds to weak to hold, DNA-RNA hybrid dissociates AKA intrinsic termination
hope this help
Answer:
d. shrimp
Explanation:
shrimp is not fish it is a shellfish along with crabs, lobsters, and crayfish.
Answer:
There are two kinds of cellular communication: communication between cells is called intercellular signaling, and communication within a cell is called intracellular signaling.
Explanation:
Answer:
it is c the answer is C ok thanks
If B and b are the two alleles , B + b = 1 and B ^2 +2 Bb + b ^2 = 1.
If 16% of mice are homozygous black , B ^ 2 =0 .16, meaning B = 0 .4 and b = 1 - 0. 4 = 0 .6 .
Answer = Notice how you don't even need to know that 24% of the mice are heterozygous .
