Among enzymes required for DNA replication,ligases are needed to form ____ bonds between to join nucleotides to DNA segments.

Question

Quizplus · Accepted Answer

Ligases are enzymes that catalyze the formation of covalent bonds between adjacent nucleotides on the same strand of DNA. They are crucial for sealing breaks or nicks on the sugar-phosphate backbone during DNA replication, repair, and recombination. Covalent bonds involve the sharing of electrons between atoms, which results in a strong bond that can withstand the forces of the cellular environment. Therefore, it is the best choice among the given options.
