whats the difference between the leading and the lagging strand?
Which replication protein links the Okazaki fragments of the lagging strand?
DNA ligase
what do single strand binding proteins do for the process?

What is the purpose of DNA proofreading during DNA replication?
makes sure the DNA is accurate and the proofreading detects and corrects errors in replication.
what is the role of telomeres?
protect the chromosomes and keep them stable
