Answer:
Regulatory gene
Explanation:
Transcription is one of the major processes that occurs during gene expression. It is the transfer of the genetic instructions in DNA to mRNA. A strand of mRNA is made using complementary base pairs.
However, there is need for gene expression to be regulated.
Gene regulation refers to the mechanism that acts to induce or repress the expression of a gene. These include structural & chemical changes to the genetic material, binding of proteins to specific DNA elements to regulate transcription. These proteins that influences transcription by binding to specific nucleotide sequences (DNA segments/gene) are referred to as REGULATORY PROTEINS and those involved in regulating transcription of genes are called TRANSCRIPTION FACTORS.
Regulatory proteins controls the rate and manner of gene expression by binding to specific genes, thus, making it easy or hard for RNA polymerase (enzyme that attaches to DNA to synthesize mRNA molecule) to bind to the promoter of that gene.
Transcription factors (regulatory proteins) that promote gene transcription are called ACTIVATORS while those that decrease are called REPRESSORS.

I hope this makes sense on how to transcribe a DNA strand. At first, it may seem hard on how to do this but if you practice transcribing a strand you will fully understand it. To remember what goes with what it is that adenine is pair with thymine while guanine is pair with cytosine. I hope this makes sense and I wish you the best in your science class.
