What enzyme makes DNA replication so accurate? How is accuracy assured?
Homework Answers
The cell has multiple mechanisms to ensure the accuracy of DNA replication. The first mechanism is the use of a faithful polymerase enzyme that can accurately copy long stretches of DNA. The second mechanism would be for the polymerase to catch its own mistakes and correct them. Stem cells have an extra safeguard to preserve the accuracy of their genetic information. DNA is double-stranded. The strands split apart and serve as templates for new copies. Every time a stem cell replicates its DNA and splits into two cells, the cell that remains a stem cell will keep the same strand of DNA. This strand is called the mother strand or the immortal strand. In this way, the stem cell can preserve the original copy of its DNA.

1. DNA Replication (10 Pts.) Create your own strand of dsDNA being sure to indicate 3’ and 5’ ends. Tell me how DNA is replicated including how bases pair. Show me DNA replication using your strand (this can be hand drawn). What enzymes are used to actually make the new DNA? How is the DNA primed for replication? What enzyme is responsible for this? What enzyme removes the primer and fills in the gap with DNA? What enzyme covalently bonds...

DNA Replication - Describe the process of DNA replication in a well-organized manner. Start with the helicase and go through the entire process, step by step. Use these terms correctly: Helicase, DNA primase, single stranded binding proteins, DNA polymerase I, DNA Polymerase III, leading strand, lagging strand, okazaki fragments, ligase, topoisomerase, sliding clamp, clamp loader. Please use correct descriptions of the enzyme function. For example, do not say, “seals nicks.” Tell me what “seals nicks” means.
