The gap between two dna fragments is sealed by what?
enzymes
reductase
rna ligase
by dna ligase
DNA polymerase starts adding nucleotides to the 3'-OH end of the primer. Elongation of both the lagging and the leading strand continues. RNA primers are removed by exonuclease activity. Gaps are filled by DNA pol by adding dNTPs. The gap between the two DNA fragments is sealed by DNA ligase, which helps in the formation of phosphodiester bonds. Table 14.1 summarizes the enzymes involved in prokaryotic DNA replication and the functions of each.
