Which of the following is not a cloning vector?
BAC
YAC
pBR322
Probe
The correct answer is:
Option 4) Probe
A probe is not a cloning vector. It is a short, single-stranded DNA or RNA molecule that is used to detect a specific sequence in a sample. It is not used for the replication and cloning of DNA fragments like the other options (BAC, YAC, pBR322) which are commonly used cloning vectors.
