Transcription is the transfer of genetic information from DNA to RNA, and it happens in the nucleus. We can automatically rule out B. B is incorrect because it doesn't make sense; how can a process stop before it even begins?
A. I believe this is incorrect because mRNA is involved when the genetic information needs to leave the nucleus. mRNA would take it to a ribosome outside of a nucleus. Since transcription happens in the nucleus, mRNA is irrelevant before it starts.
C. This doesn't really make sense. mRNA carries information from the DNA, but not vice versa (in these early stages).
D. This would make the most sense, since RNA polymerase needs to attach to the promoter on the strand before transcription can begin.
Answer:
well really it's all of them except D. and i think this should serve as a reminder to help protect are environment and have a great day
Answer:
<h2> any organism containing the DNA of interest</h2>
Explanation:
- Such type of process in which the modification of the genes of the organisms takes place is known as genetic modification and also called genetic manipulation or genetic engineering.
- In such type of the process, the branch of biological science that is known as biotechnology is used.
- In this mechanism, genes of interest are separated from the certain organism and then this gene of interest is inserted into the host organism and such type of DNA that is formed after the addition of foreign genes or DNA is called recombinant DNA.
- Such type of DNA is used in the production of genetically modified organisms and some other fields for the benefit of human beings.
Answer:
Option A
Explanation:
Thyroid is primarily caused by lack of iodine but there are other reasons as well that lead to increased size of the thyroid gland. Some of these reason is
a) over- or underproduction of thyroid hormones
b) Nodules in the glans
Some times, due to overstimulation immune system itself attack the thyroid gland thereby producing excess thyroxine and hence causing the thyroid to swell
Thus, Option A is correct
Answer:
they both have incorrect parts
Explanation:
a is wrong because they could not have ANY of the traits as none of the parents could have the spotted trait
b is wrong because it could be possible that some will have long legs because ome of the parents has long legs
