During lagging strand synthesis, DNA ligase I connects the Okazaki fragments, following replacement of the RNA primers with DNA nucleotides by DNA polymerase δ. Okazaki fragments that are not ligated could cause double-strand-breaks, which cleaves the DNA.

During this process, RNA and DNA primers are removed, allowing the Okazaki fragments to attach to the lagging DNA strand.

During 1963, he and Pauling invented the term " semantides " for biological sequences — DNA, RNA, and polypeptides — that have evolutionary information and argued that such sequences could be the basis for constructing molecular phylogenies, suggesting that the " molecular clock " method might be useful for other semantides besides proteins.
