Which of the following is not a cloning vector?

  1. Probe
  2. BAC
  3. YAC
  4. pBR322
#2

The correct answer is 1) Probe. Probe is not a cloning vector. It’s actually a short single-stranded DNA or RNA molecule that is labeled with a detectable marker and used to identify a specific DNA sequence, RNA sequence, or protein in a sample. It is not used for cloning and replication of DNA fragments in the same way that vectors like BAC (Bacterial Artificial Chromosome), YAC (Yeast Artificial Chromosome), and pBR322 are.
