DNA Replication occurs on both prokaryotes and eukaryotes. Although they have a similar genetic flow, there are small differences in between. What are the differences of DNA replication in prokaryotes and eukaryotes? What is/are the major difference/s?
Below is a diagram of DNA replication as currently believed to occur in E. coli. Arrows start from numbers and end at specific points. Answer the questions relating to the locations specified by the numbers
(1) Which end (5' or 3') of the molecule is here?
(2) Which enzyme is probably functioning here to deal with supercoils in the DNA?
(3) Which enzyme is probably functioning here to unwind the DNA?
Describe the structure of DNA.
The two strands of DNA are antiparallel. What does the term antiparallel mean?
Describe how DNA is tightly packaged. Your description should include the terms histones, chromatin, nucleosomes and chromosomes.
