1)The transition temperature, Tm, of a sample cell's membrane was found to be much lower than a reference cell's membrane. What can be said about the membrane contents of each based on this experiment?
The reference cell likely has a higher cis-fatty acid content than the sample cell.
The reference cell likely has a higher saturated fatty acid content than the sample cell.
The reference cell likely has a higher polyunsaturated fatty acid content than the sample cell.
The reference cell likely contains lower amounts of cholesterol than the sample cell.
2)How many of the following statements about DNA are true?
A-DNA and B-DNA form left-handed helices.
G and C nucleotides base pair with two hydrogen bonds.
The phosphodiester bonds that link adjacent nucleotides join the 3âhydroxyl of one nucleotide to the 5â of the next.
The two strands run in a parallel fashion.
All monosaccharide units lack an âOH at C-2â
