The promoter and terminator regions of genes are important in:

  1. a. coding for amino acids
  2. b. gene regulation
  3. c. structural support for the gene
  4. d. intron removal
  5. e. anticodon recognition

Summary Introduction

Introduction: The DNA contains various regions such as promoter, and terminator, which facilitates transcription process. These regions have crucial role during transcription process to produce genetic transcripts.

Explanation of Solution

Reason for correct answer:

A promoter region is a segment of DNA that signals for activating transcription process of a gene, or signals for inhibiting its transcription process, depending on the bound protein. The terminator region is a portion of gene that’s marks for termination of transcription process. Both promoter and terminator are necessary to control the gene expression.

Option b. is given as, “gene regulation”

The promoter and terminator portion of genes helps in regulation of genes. Hence the correct answer is an option b..

Reasons for incorrect answer:

Option a. is given as, “coding for amino acids”

The promoter and terminator region do not code for amino acid, they are site for activation of transcription process. Hence, option a. is incorrect...
