Compare and contrast p-dependent and p-independent termination of transcription in prokaryotes.
iVinArrow [24]
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

Which of the following is not an environmental impact of resource extraction? a. loss of soil b. increased resource supply c. wa
jeka57 [31]

The correct answer is - increased resource supply.

The resource extraction is a process though which the supply of resources on the market is achieved. In the past century, the extraction has been increasing constantly, thus the supply of resources on the market increased significantly because the demand for the same increased significantly.

On the other hand, the extraction of resources, very often, has very bad impact on the environment. The soils are destroyed, which is especially concerning considering the fact that fertile soils are desperately needed. The vegetation is cleared or polluted to a degree where it dies out, and the water also gets contaminated. Lot of this issues are extremely serious, and urgent measures have to be taken in order for such damage to be stopped.

tree and nest
If a robin builds a nest in a big tree, the robin benefits and the tree is not helped or harmed. This type of symbiotic relationship is called commensalism, and it is between the tree and the nest/Robin.

<span>There are several types of biotic relationships that is occurring every single moment in the ecosystem and commensalism is one. In contrast, parasitism is the biotic relationship where one organism doesn't benefit from the other and is harmed. In this scenario with human beings and mosquitos, this phenomenon of interaction is distinguished as parasitism where mosquitos draws blood that contains nutrients from the human tissue to use it as its source of food and then leaves harmful substances and bacteria in the human’s blood stream.<span> </span></span>
