Nucleotides are comprised of: a nitrogenous base and a phosphate group a nitrogenous base and a five carbon sugar a five carbon sugar and a purine a nitrogen base, a phosphate group, and a five carbon sugar Question 2 The difference between the two sugars in DNA and RNA is that the sugar in DNA can form a double stranded molecule. contains less oxygen. has a six membered ring of carbon and nitrogen atoms. Question 3 \( 0.5 \mathrm{pts} \) The two individual strands of a double helix of DNA are held together by (note: adenine = A: cytosine \( =\mathrm{C} \), thymine \( =\mathrm{T} \); guanine \( =\mathrm{G} \) ) Two hydrogen bonds between \( A \) and \( T \), and three hydrogen bonds between \( C \) and \( G \) Three hydrogen bonds between \( A \) and \( C \), and three hydrogen bonds between \( T \) and \( G \) Two hydrogen bonds between \( A \) and \( G \), and three hydrogen bonds between \( C \) and \( T \) One hydrogen bond between the sugar phosphate backbones of each nucleic acid strand hydrogen bonds between \( C 1 \) and \( C 5 \) of the sugars in adjacent nucleotides Which of the following is true concerning saturated fatty acids? They have double bonds between the carbon atoms of the fatty acids They have a higher ratio of hydrogen to carbon than unsaturated fatty acids They are usually liquid at room temperature They are usually produced by plants Question 5 \( 0.5 \mathrm{pts} \) Which of the following statements best summarizes structural differences between DNA and RNA? RNA is a carbohydrate while DNA is a steroid DNA is made of diphosphate groups whice RNA is made of mencohosphate groups DNA contains thymine and RNA dces not, Question 6 \( 0.5 \mathrm{pts} \) Which type of lipid is most important in biological membranes? wax phosphollipids ois blipierides fats
