Question

Quizplus · Accepted Answer

The enzyme that joins Okazaki fragments is ligase. Okazaki fragments are short, newly synthesized DNA fragments that are formed on the lagging strand during DNA replication. Ligase plays a crucial role in sealing the gaps between these fragments by catalyzing the formation of phosphodiester bonds between adjacent nucleotides. This results in the formation of a continuous strand of DNA on the lagging strand. Primase helps to synthesize short RNA primers on the lagging strand, DNA polymerase adds nucleotides to the RNA primers while Helicase unwinds the double-stranded DNA molecule by breaking the hydrogen bonds between complementary nucleotides, and ATP synthase helps to produce ATP by using the energy released during the oxidative phosphorylation. However, none of these enzymes are involved in joining Okazaki fragments.
