Biotechnology Principles And Processes Question 2
Question: Which of the following is not a cloning vector?
(1) Probe
(2) BAC
(3) YAC
(4) pBR322.
Show Answer
Answer: (1) Probe
Explaination-
BAC (Bacterial artificial chromosome)- useful for studying large viruses because the DNAs of these viruses are too large to be cloned in individual plasmids
YAC (Yeast artificial chromosomes)- genetically engineered chromosomes derived from the DNA of the yeast.
pBR322- a commonly used plasmid cloning vector in E. coli
Probe- a single-stranded sequence of DNA or RNA that is used to identify specific sequences of DNA or RNA
