Why it is important to place the gel in the correct direction in the gel cassette while running it? 1. 2. sketch a gel showing the running pattern of same sized dna that is, linear, circular and circular-supercoiled sketch a gel showing the running pattern of three linear dna pieces with 100bps, 500bps and 1000bps 3. what is the importance of loading dye?

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
