Question
True -a, Falseb ransposons are flanked by both inverted repeat sequences and also direct repeated Its in an overall increase 25. The mode of insertion of a retrotransposon ultimately resu in the number of copies of the retrotransposon in the genome. 26. The technique used this given week in lab is the same technique used in paternity except that more loci are used in these latter tests and crime scene investigations, two. Lab 14: Population Genetics-Gel Electrophoresis Multiple Choice 27. During gel electrophoresis, DNA runs toward the_end a) positive b) negative neutral d) all of these e) none of these 28. When visualizing DNA, ethidium bromide (or Gelstar)... a) attaches to the phosphate backbone. b) surrounds the DNA c) inserts in between the bases of the DNA double helix. d) replaces G bases of the DNA e) replaces C bases of the DNA 29, when using 50ml of TAE buffer to create a 1.5% agarose gel, how many grams of agarose should be measured? a) 3 grams b) 0.15 grams )1.5 grams d)7.5 grams e)0.75 gramsExplanation / Answer
Answer:
25) The mode of insertion of a retrotransposon ultimately results in an overall increase in the number of copies of the retrotransposon in the genome - TRUE (a) Explanation: Replicate mode of transposition increases the copy number of retrotransposon elements in the genome)
26) The technique used this given week in the lab is the same technique used in paternity tests and crime scene investigations, except that more loci are used in these latter two. -- **Need more details about Lab technique to answer this part.
27) During gel electrophoresis, DNA run towards the positive end. (Explanation: DNA is negatively charged molecule due to the presence of phosphate backbone. Therefore, when placed in an electric field, DNA will move towards the positive anode end).
28) When visualizing DNA, ethidium bromide (or Gelstar)
29) When using 50ml of TAE buffer to create a 1.5% agarose gel, how many grams of agarose should be measured?
