WebAug 14, 2024 · Those DNA molecules that had completed synthesis at each time point were isolated, cut with a restriction endonuclease, and assayed for radioactivity in each fragment. This restriction endonuclease cleaves the circular DNA into 6 fragments, named A, B, C, D, E, and F in a clockwise orientation around the genome. WebJul 25, 2024 · The scientific community has identified two crucial functions of DNA polymerase during cell division. It helps in the replication of DNA, ensuring that each new cell receives a complete set of genetic instructions. DNA polymerase assists in the repair of damaged DNA, helping to protect the cell against genetic mutations. WebWhen the replication fork reaches the end of the linear chromosome, there is no place to make a primer for the DNA fragment to be copied at the end of the chromosome. These ends thus remain unpaired and, over time, they may get progressively shorter as cells continue to divide. slums score 11/30
