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 […]

1. A diploid somatic cell from a new species of octopus has a totalof 62 chromosomes (2n = 62). Answer the following questions: A. How many different chromosomes (i.e. carrying differentgenes) does it have?B. How many molecules of DNA are in the nucleus of its somaticcells in G1?C. How many […]

Experiment 1: Labeling Questions 1. For each structure identified, do you think its location affects its ability to function? Why or why not? (Hint: those buried deep in the cell probably do different things than those closer to the cell membrane) 2. Draw a labeled diagram of a small section […]
