Questions & Step-by-Step Solutions

In cloning, what is the role of a vector?
Correct Answer: A vector is a DNA molecule used to deliver foreign genetic material into a host cell for cloning purposes.
  • Step 1: Understand that cloning involves making copies of DNA.
  • Step 2: Know that a vector is a special tool used in this process.
  • Step 3: Realize that a vector is a DNA molecule that can carry other pieces of DNA.
  • Step 4: Learn that the vector delivers foreign genetic material into a host cell.
  • Step 5: Recognize that once inside the host cell, the foreign DNA can be replicated or expressed.
  • Vector in Cloning – A vector is a DNA molecule that carries foreign genetic material into a host cell, facilitating the cloning process.
