Answer:
A promoter is a region of DNA where transcription of a gene is initiated. Promoters are a vital component of expression vectors because they control the binding of RNA polymerase to DNA. RNA polymerase transcribes DNA to mRNA which is ultimately translated into a functional protein.
Explanation:
They are sandwiched between two layers of heads. Recall that the heads are hydrophilic therefore they will always be on the outside and the tails are hydrophobi therefore they willl always be away from water, there fore sandwiched. I'm a bio major, hope I helped :)
<span>A scientist wants to create a florescent ornamental fish. He needs fluorescence similar to that of a firefly. Which of the send processes would help him create this fish?
The correct answer is </span><span>transformation of the DNA of a fish using a fluoroscent gene from a firefly. In order to do so, he would have to use the gene of the firefly as a reference in order to transform the DNA of a fish.</span>
Answer:
A trait is most likely to exhibit continuous variation if it is controlled by <em>many gene loci, each with several possible alleles.</em>
