Q23: Dr. Alghe has just performed a restriction digest on DNA she extracted from her samples. She must now run her DNA out on a gel to separate the fragments based on size. To do this she must prepare a 1.1% agarose gel, where the percentage is determined as mass/vol. How many grams of agarose must she add to 413 mL of buffer in order to arrive at the correct percentage? (answer to 2 decimals) **Assume the dissolution of agarose will not alter the final volume of the solution**
DNA Replication1) Construct the complementary strand of DNA (strand II) that would pair with the DNA strand I sequence below. Remember that nucleotides are always added in the 5 prime to 3 prime direction. The base pairing rules are: DNA DNAadenine (A) always bonds with thymine (T) thymine (T) always bonds with adenine (A) guanine (G) always bonds with cytosine (C) cytosine (C) always bonds with guanine (G) STRAND I: 3’ T A C T A T A G T C T G T C T C C C A C T 5’ STRAND II: 5’ 3’

Determine the branch points and reducing ends of amylopectin. A 0.5g sample of amylopectin was analyzed to determine the fraction of the total glucose residues that are branch points in the structure. The sample was methylated and then digested, yielding 50 μmol of 2,3-methylglucose and 0.4 μmol of 1,2,3,6-tetramethyl glucose. (MWglucose = 162 g/mol, minus H2O) What fraction of the total residues are branch points? How many reducing ends does the amylopectin have?
