You are studying a genome that has 42% G:C content and the remaining 58% of the genome is As and Ts. Assuming a random distribution of these bases what is the expected distance (ie there will be a cut once in every XX base pairs) between cut-sites for restriction enzyme that cuts at the sequence GAATTC? 256 3207 4168 O 4096

Can you please help with 1c please  picture with 1 graph is for question 1a) picture with 4 graphs is for question 1b) 1a) E. coli DNA and binturong DNA are both 50% G-C. If you randomly shear E. coli DNA into 1000 bp fragments and put it through density gradient equilibrium centrifugation, you will find that all the DNA bands at the same place in the gradient, and if you graph the distribution of DNA fragments in the gradient you will get a single peak (see below). If you perform the same experiment with binturong DNA, you will find that a small fraction of the DNA fragments band separately in the gradient (at a different density) and give rise to a small "satellite" peak on a graph of the distribution of DNA fragments in the gradient (see below). Why do these two DNA samples give different results, when they're both 50% G-C? 1b) If you denatured the random 1000 bp fragments of binturong DNA that you produced in question 1a by heating them to 95ºC, and then cooled them down to 60ºC…

Assuming that the mean size of the human sau3AI partially digested fragments clones is 3kb, calculate the proportion of the human genome represented in all libraries prepared by the class. Use a value of 3,000,000kb for the size of the human genome. You also need to know that the whole 'class' generated 3,514 white colonies on plate 2.

You are a researcher studying a gene you think is responsible for super human strength. You call the gene HULK1. Below is the ORF of this gene from a normal strength individual (with nucleotide position indicated above). Use this sequence to answer the following questions. 1 10 20 30 39 5'- ATG TCA AAG GAC ATT CGC TGT GGG CTC AGA CTA TCA TAA -3' You design primers (6nt each) to amplify this entire sequence. Which primer set below did you use? O a. 5-TTATGA-3' and 5'-TGACAT-3' Ob.5'-TGACAT-3 and 5'-TCATAA-3' Oc 5'-ATGTCA-3' and 5'-TCATAA-3' Od. 5'-ATGTCA-3' and 5'-TTATGA-3' Oe. 5'-ATGTCA-3' and 5'-TGACAT-3'
