Question

Which of the following is not a cloning vector?

Options

• YAC

• pBR322

• Probe

• BAC

Answer 1

Probe

Explanation:

Probe is not a cloning vector. A single-stranded DNA or RNA sequence identifies certain sequences. These are meant to supplement the gene of interest. This ensures that the probe hybridises with the target sequence when combined with the genome. YAC, Pbr322, and BAC are cloning vectors. These are plasmids that spread DNA. They inject foreign DNA into other cells.
