- During agarose gel electrophoresis, why does DNA move through the gel when electric current is applied? because DNA is negatively charged because a charged chemical from the loading buffer is bound to the DNA because DNA is positively charged because DNA absorbs electricityWhat is the role of GelRed® in Agarose gel electrophoresis of DNA fragments? Please select the single answer that is most correct GelRed® moves down the agarose gel in response to the electric current and enables visualisation of the position of A the nucleic acids within in the agarose gel. GelRed® intercalates with the Nucleic acid and, under UV light, fluoresces to enable visualisation of the position of the nucleic acids in the agarose gel. GelRed® intercalates with the Nucleic acid and enables visualisation of the position of the nucleic acids in C the agarose gel. GelRed® intercalates with the amino acids in the agarose gel and enables visualisation of the position of their in D the agarose gel.Which one of the following options would be a good way to identify the location of the poly A tail in the published DNA sequence for a gene? Look for AATAAA near the 3’ UTR of the DNA sequence. Look for TTTTTTTTTTTTTT… (many Ts) near the 3’ UTR of the DNA sequence. Look for AAAAAAAAAAA… (many As) near the 3’ UTR of the DNA sequence. Look for a stop codon.

- based on the picture What is the length in basepairs of these sequences? How many base substitutions are there between these sequences? Count ONLY the instances where there is ANY nucleotide difference between any of the sequences (leave out any indels in this count) Are there any indels in this alignment? (yes or no)Choose the correct gel electrophoretic pattern that would be seen in dideoxy sequence analysis of the DNADNA molecule shown below. pGGCGACCGATTAGTCCCATCGATGGG−OHEthanol (CH3-CH2-OH) is miscible in water because it is able to form hydrogen bonds with itself and other molecules. However, its structure only allows it to form 1-2 hydrogen bonds. This is one reason why even low concentrations of ethanol in solution are lethal for cells. Based on this information, explain why we can use high concentrations of ethanol to precipitate DNA out of solution. Also, describe/predict the effects of increasing concentrations of ethanol in (and around) a cell on macro-molecular interactions (i.e. on weak bonds). Finally, it is possible to select for yeast that are tolerant to increased concentrations of ethanol. Give an example of a physiological change in yeast cells that might make them resistant to ethanol.
