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.
It would be hypotonic so the second one
Answer:
Endometrosis could negatively affect the probability of gestating an embryo if they are growing inward. The affection of the fallopian tubes and the uterus could alter the implantation or even generate complications for the embryo during pregnancy.
In addition, endometriosis generates painful conditions in the abdominal area to the point that it is considered as menstrual cramps during menstruation, women who suffer from this disease suffer a lot during the menstrual cycle.
Regarding the reproductive system, those female reproductive systems that suffer from this disease are considered potentially malignant, since many malignant neoplasms are incited to appear in these foci of excessive proliferation of the endometrium.
Explanation:
Endometriosis can affect the walls of the fallopian tube and the uterus, since it occurs in the endometrium, that is why it bears that name.
The macroscopic appearance of this lesion at the histological level is a tumor nodule, since they are proliferative foci.
Answer:
Helper.
Explanation:
I will take the position of helper that work for the betterment of environment by reducing such activities that can increase the carbondioxide concentration in the atmosphere. The main reason for this position is the destruction and damages that occurs in the environment and to organisms that are present all around the world. This global warming leads to the extinction of these species so in order to protect them I choose this position.
