Questions & Step-by-Step Solutions
In cloning, what is the purpose of using a vector?
Correct Answer: Vectors are used to introduce foreign DNA into host cells.
Step 1: Understand that cloning involves making copies of DNA.
Step 2: Know that sometimes we want to insert a piece of DNA from one organism into another organism.
Step 3: A vector is a tool that helps carry this foreign DNA into the host cell.
Step 4: The vector can be a plasmid (a small circular DNA) or a virus that can infect the host cell.
Step 5: Once the vector is inside the host cell, it allows the foreign DNA to replicate and be expressed, meaning the host cell can make the proteins coded by the inserted gene.
Step 6: This process is important for research, medicine, and biotechnology.
