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.
The correct option is C, ROUND WORM is a pseudoceolomate. Pseudoceolomate have a body cavity surrounding the gut but the gut itself is not surrounded by mesoderm; generally, their body cavity are lined by mesoderm derived tissue on one side and endoderm derived tissue on the other side. Other examples of pseudoceolomate are hook worm, hair worm, rotifers and pinworm. They are mostly parasitic in nature.
