Question

When dna polymerase progresses during dna replication, how is the correct new nucleotide selected to be next?.

Answer 1

DNA polymerase chooses nucleotides that undergo proper base pairing with the corresponding base on the template strand.

• The family of enzymes that catalyze the synthesis of DNA molecules from nucleoside triphosphates, the basic building blocks of DNA, includes DNA polymerase.
• These enzymes, which are necessary for DNA replication, often function in groups to split a single original DNA duplex into two identical DNA duplexes.
• A primer sequence is introduced with complementary RNA nucleotides to provide this beginning point because DNA polymerase can only add new nucleotides at the end of a backbone.
• Later, the primer is taken out, and DNA nucleotides are used in its place.
