Draw a diagram showing a portion of a chromosome
undergoing replication. Label the leading and lagging strands, and
replication fork. What are the roles of DNA polymerase and RNA
polymerase? How does this process represent semi-conservative
replication?
Homework Answers
DNA polymerase is the enzyme which using the DNA template for the formation of daughter DNA molecule.
RNA polymerase is the enzyme which uses DNA template for the formation of RNA molecule.
DNA replication is semiconservative process because in the daughter DNA molecule, one of the strand is of parental origin whereas the other is newly synthesized molecule.
Please rate high.

1) Draw a diagram of a bacterial replication fork showing the leading and lagging strand of new DNA and the enzymes responsible for the processes involved. Indicate the 3' and 5' end of each nucleic acid strand. 2) The ends of a linear chromosome cannot be replicated by the normal DNA replication enzymes. Why? How does the eukaryotic cell solve this problem?
