Answer:
The correct answer is option E. "nucleotides can only be added to an available 3'-OH group on the transcript terminus".
Explanation:
RNA synthesis is catalyzed by an enzyme called RNA polymerase. RNA polymerase always catalyze the synthesis of new RNA from 5' to 3' because nucleotides can only be added to an available 3'-OH group on the transcript terminus. This has been confirmed in labeling experiments with γ-32P substrates which establish the presence of a triphosphate moiety in transcripts with either pppG or pppA.
The use of prokayotes and other organisms to clean up pollutants from soil, air, or water is called Bioremedation. Bioremedation is the use of living organisms for the recovery or cleaning up of a contaminated medium such as soil, sediment, air and water. It is actually a waste management technique that neutralizes pollutants from contaminated site using organisms. examples of bioremedation related technologies are mycoremedation, phytoremedation among others.
The best description about the brain stem is: it is the most important organ of our body's survival. It connects the brain and the spinal cord, controls the vital organs like the lungs and heart and it also coordinates the many essential body reflexes.
Answer:
Round Mountain is an epithermal, low-sulphidation, volcanic-hosted, hot-springs deposit located along the margin of a buried caldera. The majority of the mineralisation at Round Mountain is contained within the tuffs, although drilling has encountered some ore in the underlying Palaeozoic basement.

The answer is 3:1.
If we imagine that plant has two alleles for the
trait, we can dominant allele represent with P represents and recessive allele with p. To get purebred monohybrid in the first generation, parents must be a dominant homozygote (PP) and a recessive hetero<span>zygote (pp):
Parental generation: PP x pp
The first generation: Pp Pp Pp Pp
Pp represents a heterozygote.
If we cross these heterozygotes:
The first generation: Pp x Pp
The second generation: PP Pp Pp pp
If dominant allele determines the phenotype, there will be 3 plants (one PP and two Pp) with one phenotype and only 1 plant </span><span>(pp)</span> with another phenotype and vice versa.
