Explanation:

AP3X

The correct option for the given question about Genetic transcription is Option B) RNA polymerase reaches the beginning of a gene.

What is Genetic Transcription?

  • It is one among the initial steps in the expression of genes. The transport of genetic information from DNA to proteins occurs sequentially through the processes of transcription and translation.
  • During transcription, just one strand of DNA known as the template strand is replicated, and the resulting RNA is referred to as messenger mRNA.
  • Transcription's primary goal is to create an RNA copy from a DNA sequence. The data required to encode a protein is carried by the RNA transcript.
  • RNA polymerase is the key enzyme responsible for Genetic transcription.
  • It creates a complementary RNA strand from single strand DNA.

Thus we conclude that during the first step of genetic transcription RNA polymerase reaches the beginning of a gene.
