Commonly used vectors for human genome sequencing are:

1. T-DNA
2. BAC and YAC
3. Expression Vectors
4. kT/A Cloning Vectors

Correct answer: BAC and YAC

Solution

BACs and YACs can clone very large pieces of DNA, which made them useful for constructing genomic libraries and sequencing whole genomes. The other options are mainly used for gene transfer, expression, or routine cloning of smaller fragments.
