1 Read same on two strands when orientation of reading is different
2 Read different on two strands when orientation of reading is same
3 Read same on two strands when orientation of reading is same
4 Read opposite on two strands when orientation of reading is same
Explanation:
The palindrome in DNA is a sequence of base pairs that reads same on the two strands when orientation of reading is kept the same.

The role of DNA ligase in the construction of a recombinant DNA molecule is:
1 Formation of phosphodiester bond between two DNA fragments
2 Formation of hydrogen bonds between sticky ends of DNA fragments
3 Ligation of all purine and pyrimidine bases
4 None of the above
Explanation:
DNA ligase facilitates the formation of phosphodiester bond between two sticky ends of DNA fragments.

Statement A : Restriction enzymes Hind II is obtained from Haemophilus Statement B : The first restriction endonuclease-Hind II
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Hind II was the first discovered restriction endonuclease enzyme. It has been isolated from Haemophilus influenzae. It cuts DNA molecules at a particular point by recognising a specific sequence of six base pairs. This specific sequence is known as the recognition sequence for Hind II. Both statements are correct.
