Cloning Genes Is a Multistep Process

Which enzyme is responsible for covalently linking DNA strands together?

  1. a. DNA polymerase
  2. b. DNA ligase
  3. c. EcoRl
  4. d. restriction enzymes
  5. e. RNA polymerase

Summary Introduction

Introduction: The double strands of DNA molecule are linked together by hydrogen bonding in between the complementary nucleotide bases. These nucleotide bases form the backbone of the DNA molecule. The complementary bases are of four types A, T, G, and C, and each base is liked either through double or triple bonds.

Explanation of Solution

Reason for correct answer:

The function of joining of new or ruptured bonds in the strands of DNA molecule is performed by “DNA ligase.” It catalyzes the formation of phosphodiester bonds between two nucleotides. The formation of bonds in between the nucleotides results in the formation of a long chain of polynucleotide which leads to the formation of different strands of DNA.

Option b. is given as “DNA ligase.”

An enzyme which is responsible for the covalently linking the strands of DNA together is known as “DNA ligase.” Hence, the correct answer is option b.

Reason for incorrect answer:

Option a. is given as, “DNA polymerase.”

DNA polymerase results in the addition of nucleotides to the growing chain of DNA strand during the synthesis of DNA...
