  3. CYAC - Can clone fragments upto 45 kb45 \mathrm{~kb} in length only
  4. DPhagemid - An RNA based cloning vector carrying an origin of replication derived from adenovirus.

Correct answer

B. BAC−300−350 kb\mathrm{BAC}-300-350 \mathrm{~kb} of foreign DNA

Step-by-step solution

Bacterial artificial chromosome (BAC) vectors are based on natural, extra-chromosomal plasmid of E.coli. These vectors can accommodate upto 300−350 kb300-350 \mathrm{~kb} of foreign DNA and are also being used in genome sequencing project.
