Question

What is the function of a vector in genetic engineering?

Options

• Cut DNA into many fragments

• Carry DNA into a new cell

• Link together newly joined fragments of DNA

• Make millions of copies of a specific segment of DNA

Answer 1

Carry DNA into a new cell

Explanation:

Vectors serve as vehicles that transfer foreign DNA into host cells, allowing the DNA to be replicated or expressed. They are essential tools for cloning and gene transfer, facilitating the introduction of recombinant DNA into organisms. Common vectors include plasmids and viruses, which can efficiently deliver genetic material into the target cells for further replication or expression.
