Question

which enzyme covalently links nucleotides together?
o dna gyrase
o dna polymerase
o dna topoisomerase
o helicase

Explanation:

DNA polymerase catalyzes the formation of phosphodiester bonds between nucleotides during DNA replication, covalently linking them together. DNA gyrase and topoisomerase manage DNA supercoiling, and helicase unwinds the DNA double - helix.

Answer:

B. DNA polymerase
