State whether the following statements is true/false regarding DNA replication.
1. A short primer is added to the DNA polymerase reaction mix for Sanger DNA sequencing that has a 5สน free hydroxyl to which new nucleotides can be added.
2. In a sequencing gel, all fragment in one of the four lanes terminates in the same type of nucleotide base.
3. Eukaryotic cells contain at least five DNA polymerases all of which are responsible for nuclear DNA replication.
4. Since the rate of form movement in eukaryotes is much slower than that of bacteria, chromosomes require more than an hour to replicate.
5. Although histones and DNA are made in the same parts of the eukaryotic cell, the packaging of them in the nucleosome slows down replication so that it is slower than that of prokaryotes.
