A researcher combines a variety of molecules needed for DNA replication. After adding DNA to the mixture, replication occurs, but each resulting DNA molecule consists of a long DNA strand paired with segments of DNA ranging from 10-350 nucleotides long. What did the researcher likely leave out of the mixture? DNA ligase O primase Okazaki fragments
