This gel shows the products of amplification of TPA25, just as you did in lab, for several people (The molecular weight standards are in the last lane on the left). The number of people that are homozygous for the alu insertion is A. 1 B. 2 C. 3 D. 5 E. 6 5. Make a slide of these microorganisms and examine it to determine if they are motile or non-motile and roughly how big is it in its longest dimension (you can use the slide with the ruler on it to help you estimate its size). PLEASE DISCARD THE SLIDE YOU MADE IN THE WASTE AFTER YOU FINISH A. motile; 1000 m B. motile; 100 m C. motile; 10 m D. non- motile; 10 m E. non- motile; 100 m 6.
