Answer:Describe the process and purpose of transcription. The purpose of transcription is to produce an mRNA copy of a gene, to allow the genetic information to pass out of the nucleus, through the nuclear pores where it can be used to assemble a protein.

Transcription is a first step of gene expression. In Transcription, the information in the DNA is copy  into messenger mRNA by an enzyme called RNA polymerase.

One of the purposes of transcription is to produce a sequence of bases that substitutes for essential amino acids.

Transcription

  • Transcription is completed in three stages: initiation, elongation, and termination.

  • The aim of transcription is to make copies of a gene's DNA sequence.

  • In initiation, the RNA polymerase, is bind to the DNA strand, RNA polymerase separate the DNA strand.

  • In elongation, one of the strand act as a template for RNA polymerase to transcript.

  • Then, In termination, terminators signals that transcription is completed and the RNA in the form of hairpin moves out.

  • The process repeats several times.

Thus, One of the purposes of transcription is to produce a sequence of bases that substitutes for essential amino acids.
