Questions & Step-by-Step Solutions

What is the role of reverse transcriptase in recombinant DNA technology?
  • Step 1: Understand that reverse transcriptase is an enzyme, which is a type of protein that helps speed up chemical reactions in the body.
  • Step 2: Learn that reverse transcriptase's main job is to convert RNA (a type of genetic material) into DNA.
  • Step 3: Recognize that in recombinant DNA technology, scientists often want to work with DNA, not RNA.
  • Step 4: Know that complementary DNA (cDNA) is made from RNA using reverse transcriptase.
  • Step 5: Realize that creating cDNA is important because it allows scientists to study genes and produce proteins in a lab setting.
