Commonly used vectors for human genome sequencing are

Options

A. T – DNA
B. BAC and YAC
C. Expression vector
D. T/A cloning vector

Answer

B

Explanation

Bacterial Artificial chromosomes (BAC) vector are vectors which are based on fertility plasmid of bacteria. These are used for mapping of large eukaryotic genome. They can accommodate large DNA fragments of size 300 – 350 Kb.
Yeast Artificial chromosome resemble natural chromosome. They have telomere at each end, autonomously replicating sequence and a Centromere.
