Phosphodiester bonds ligase
WebThis strand is known as the lagging strand. Once replication is completed, the RNA primers are replaced by DNA nucleotides and the DNA is sealed with DNA ligase, which creates phosphodiester bonds between the 3'-OH of one end and the 5' … WebYou'll get a detailed solution from a subject matter expert that helps you learn core concepts.

WebJun 14, 2024 · DNA ligase is an enzyme that facilitates the formation of a phosphodiester bond and joins two DNA strands. Other than DNA synthesis, the enzyme has a critical role … WebIn general, a ligase catalyzes the following reaction: Ab + C → A–C + b or sometimes Ab + cD → A–D + b + c + d + e + f where the lowercase letters can signify the small, dependent groups. Ligase can join two complementary fragments of nucleic acid and repair single stranded breaks that arise in double stranded DNA during replication.
