Match the items in Group I with Group II
Group I (Vectors):
P. λ phage
Q. Bacterial Artificial Chromosomes (BACs)
R. P1 derived Artificial Chromosomes (PACs)
S. λ cosmid
Group II (Maximum DNA packaging):
1. 35-45 kb
2. 100-300 kb
3. ≤ 300 kb
4. 5 – 25 kb
(A) P-3, Q-4, R-1, S-2
(B) P-1, Q-3, R-2, S-4
(C) P-4, Q-3, R-2, S-1
(D) P-1, Q-2, R-3, S-4
Answer
Answer: (D) P-1, Q-2, R-3, S-4
λ phage can package 5-25 kb of DNA (P-4), BACs can package 100-300 kb (Q-2), PACs can package ≤ 300 kb (R-3), and λ cosmids can package 35-45 kb (S-1).
