Linear double stranded DNA- sample LSU1- is digested with 2 restriction endonucleases (separately and together) and the following bands are observed after electrophoresis ( quantities represent length in bp): BamH1:1,9 and 13.5;EcoR1: 3, 3.5, 4, and 13. BamH1 and EcoR1: 1, 2.5, 3, 4, 5, and 8. a. How many […]

In a certain plant, fruit is either red or yellow, and fruit shape is either oval or long. Red and oval are the dominant traits. Two plants, both heterozygous for these traits, were testcrossed, with the results listed in the table. Determine the location of the genes relative to one […]

TBP is a relatively small protein (~35kDa) that can bind DNA sequences (the TATA box) on its own with relatively high affinity. However if nuclear extracts are subjected to Gel Filtration Chromatography or Zonal Centrifugation and each eluted/collected fraction is tested in a western blot it appears that TBP is […]
