Question

In order for a gene to be transcribed or read , what needs to happen ? ( 1point )

a. the promoter region of a gene is bound to its specific binding protein
b. the enhancer region of a gene is bound to its specific binding protein
c. the transcriber region of a gene is bound to its specific binding protein
d. a mutation occur in the gene

Answer 1

The answer should be "a" but it needs to read the promoter region of a gene is bound to the enzyme RNA polymerase, positioning the enzyme on the correct DNA strand.

In the process of transcription, an enzyme called RNA polymerase recognizes and binds to a DNA nucleotide sequence just before the beginning of the gene. This recognition site, called a promoter, positions RNA polymerase properly on the correct DNA strand and points it in the right direction.

The DNA strands then separate over a short distance and the polymerase moves into the gene and as it moves, it creates a new chain by linking together individual ribonucleotides existing free in the cell, This new chain or strand is called messenger RNA.
