1.Describe the rearrangement in chromosomes A-C. indicate the specific markers genes flanking the crossover/breakage points (e.g., a translocation with breakpoints between markers X and Z). 2.Chromosome rearrangements can be caused by crossing over between repetitive DNA sequences. Draw a picture similar to Figure showing how crossovers between repetitive sequences could have produced chromosome rearrangement A. indicate the location and orientation of the repetitive DNA segments relative to the marker genes.
Referring to Figure 17-26, draw the product if breaks occurred within genes A and B
DNA of different densities is distinguished by a procedure called caesium chloride (CsCI) densitycentrifugation. Spinning CsCI at high speeds for many hours generates a gradient of caesium andchloride ions. The highest ion concentration, or density, occurs at the bottom of the tube.b. In this experiment, where on the cesium chloride (CsCI) gradient would the following DNAbe found (low density, middle density, or high density):Double stranded DNA where both strands are labeledDouble stranded DNA where one strand is labeledDouble stranded DNA where neither strand is labeled
A pair of paralogous repeats, A and B, have 96% sequence similarity and therefore can promote non-allelic homologous recombination (NAHR). They exist in four possible arrangements in a genome, illustrated below as arrangements 1 – 4. What is the result of NAHR between repeats A and B in arrangement 1? A.Translocation between chromosomes 1 and 2 resulting in monocentric chromosomes B.Deletion or duplication of the region between A and B C.Translocation between chromosomes 1 and 2 resulting in acentric and dicentric chromosomes D.Inversion of the region between A and B
You are working in a biotechnology lab arid are analysing DNA. You obtain a sample of a short dodecamer of DNA that contain 12 base pairs. What must the ratio of adenine to thymine be in your sample? What must be ratio of cytosine, to guanine be in your sample? Assume the counter ions present in your DNA solution are sodium ions. How many sodium ions must there be per dodecamer? Assume the 5’ end phosphate each bear a-1 charge.
PCR is a molecular biology technique where template DNA is amplified using a primer and oligonucleotides. The reaction is catalyzed by a thermostable DNA polymerase and in a particular reaction, the template strands are denatured at 95˚C. For strand hybridization, the melting temperature is 55˚C. What do you predict about the average duration of H bonds at the high temperature in comparison to the low temperature?
