Questions and Answers

Why is the regulation of gene expression necessary?

  • To allow bacteria to express all the genes in their genome constantly
  • To control the production of specific gene products (correct)
  • To prevent the transcription and translation of genetic information
  • To increase the number of genes expressed at any one time
  • What is meant by gene regulation?

  • Controlling the expression of specific genes (correct)
  • Halting the transcription and translation processes
  • Ensuring constant production of gene products
  • Activating all genes in the genome simultaneously
  • What describes the role of regulatory proteins in gene regulation?

  • They control the expression of specific genes (correct)
  • They have no impact on gene regulation
  • They inhibit all gene expression
  • They promote constant gene expression
  • What is the difference between inducible and repressible genes?
