Error rates in DNA replication, proofreading and mismatch repair systems in E. coli are about 10-10 per base pair per round of replication. Based on this, how many mutations per base pair would you expect to see in a population of 1010 E. coli cells (e.g. of a TSB culture of E. coli)

This question is about DNA damage, repair and mutation. a) State a type of mutagen that could produce a single base pair substitution mutation. Briefly describe how this mutagen can produce single base pair substitution mutations. [4 marks] b) For your mutagen from (a), briefly describe the repair process that could repair the DNA damage. [4 marks] c) Propose how a single base pair substitution can be a hypomorphic allele. Explain how your mutation fits the definition of a hypomorphic...

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. If you speak about something you have...

JO 8-9 In the classic paper that demonstrated the semi-con- servative replication of DNA, Meselson and Stahl began by showing that DNA itself will form a band when subjected to equilibrium sedimentation. They mixed randomly frag- mented E. coli DNA with a solution of CsCl so that the final solution had a density of 1.71 g/ml. As shown in Figure Q8-2, with increasing length of centrifugation at 70,000 times gravity, the DNA, which was initially dispersed throughout the centrifuge tube,...

Question 33 2 pts Which of the following statements about the process of DNA replication is true? It involves the enzyme DNA ligase, which corrects point mutations. It utilizes DNA polymerase, which catalyzes the reaction that adds a new nucleotide to the growing strand. The sequence on the new strand is always identical to one of the old parent strands. Adenine pairs with guanine, and cytosine pairs with thymine. Question 34 2 pts The DNA base...

Food Microbiology Purpose To utilize the process of fermentation to make yogurt To describe organisms responsible for food borne illnesses and summarize a recent outbreak Introduction Microorganisms have been used for centuries for food preservation and to improve or change its taste. Evidence exists that yogurt, which is milk fermented by bacteria, has been around for over 4000 years. Today, many of the foods we eat are the result of microorganisms acting on foods for a specific and desired effect....
