Answer: Promoter
Explanation:
Transcription is the first step in gene expression which consists of copying the DNA sequence of a gene to produce a RNA molecule. There are enzymes called <u>RNA polymerases which perform this process of transcription</u>. These enzymes bind nucleotides (the monomers which are part of the nucleic acids) to create a RNA strand using a DNA strand as a mold.
A promoter is a region of DNA that controls the initiation of transcription of a given portion of DNA to RNA. Therefore they promote the transcription of a gene. <u>The promoter region is composed of a specific sequence of DNA located just where the starting point of the DNA transcription is</u> and contains the information needed to activate or deactivate the gene it regulates. <u>The promoter has a binding site for the RNA polymerase enzyme </u>in charge of mRNA synthesis and when it recognizes this site, transcription begins.
Answer: e) gain of function in disc B of some of the structures usually seen in disc A
Explanation:
it can be inferred that having a gene B and adding a gene A, it can develop forms of both patterns, since it is known that gene A does not interfere in the formation of B, which acts independently to generate its genetic characteristics Thus, the function of B will remain the same and genetic dysregulation will not occur.
Answer:they make useful substances, including: wax, honey, laquer, and silk
Explanation:
<span>Benzedrine, methedrine, and dexedrine are all amphetamines, Amphetamines are a stimulant drug to the central nervous system, usually produced in a laboratory. They are used in the treatment of hyperactivity disorder, narcolepsy and obesity amongst other things. They are also present in some banned substances for recreational use.</span>
