Options

  1. AA-III, B-I, C-IV, D-II
  2. BA-II, B-I, C-IV, D-III
  3. CA-III, B-IV, C-I, D-II
  4. DA-III, B-II, C-I, D-IV

Correct answer

A. A-III, B-I, C-IV, D-II

Step-by-step solution

According to NCERT, the components of a cloning vector have specific functions: - 'ori' (origin of replication) is a sequence from where replication starts, and it is also responsible for controlling the copy number of the linked DNA (A matches III). - Selectable marker helps in identifying and eliminating non-transformants and selectively permitting the growth of the transformants (B matches I). - Cloning sites are the recognition sites for commonly used restriction enzymes where the alien DNA is ligated (C matche
