To study DNA replication, researchers often use bacteria that harbor a temperature sensitive mutation in one of the genes related to replication. This means that when cells are grown at lower temperatures (30°C) they are fine, but when shifted to 42°C the effect of the mutation becomes evident and that protein is no longer functional. Depending on the gene mutated, researchers observe that for some replication stops almost immediately, but for others more slowly. In this question you have a...

You are a scientist studying DNA replication. You have the ability to introduce temperature-sensitive mutations into the bacteria that you are studying (temperature-sensitive mutations work normally at one temperature, but when you raise the temperature a little, the mutation exerts its effect. This allows you to grow colonies with mutations that would otherwise be lethal. The fact that these mutations are temperature sensitive has nothing to do with the problem, other than to make it accurate to how these would...

You are studying a mutant strain of bacteria in which the trp operon includes a mutation in region 1 of the 5'UTR. Whereas in the wildtype strain the affected codons code for "trp, in the mutant strain these codons code for "stop". How will this mutation affect attenuation? Translation of the S'UTR will stop at the position of the mutation in region 1. As a result, region 3 of the 5'UTR will pair with region 2 in the mRNA causing...

You have a bacterial strain with a mutation that removes the transcription termination Sinal from the A operon. Which of the following statements describes the most likely effect of this mutation on Abd transcription? The Abd RNA will not be produced in the mutant strain, On The Abd RNA from the mutant strain will be longer than normal. Sigma factor will not dissociate from RNA polymerase when the Abd operon is being transcribed in the mutant strain RNA polymerase will...

invas (2014) You prepare bacterial cell extracts by lysing the cells and removing insoluble debris via centrifugation. These extracts provide the proteins required for DNA replication. Your DNA template is a small, double-stranded circular piece of DNA (a plasmid) with a single origin of replication and a single replication termination site. The termination site is on the opposite side of the plasmid from the origin. origin plasmid termination Figure 6-11 What part of the DNA replication process would be most...

You have found a strain of microorganism, Schizosaccharomyces spp that is very sensitive to mutagenic compounds. When grown in the presence of known mutagens this organism produces many mutant progeny. This microbe, initially isolated from beer-stained carpeting from Zach’s apartment, is obviously deficient in repairing damage to DNA. You perform a series of experiments to determine which repair system is defective. A. You first take two identical cultures and expose them to 30 minutes of irradiation. You place one of...
