DNA and RNA are both examples of which type of macromolecule?

• lipid

• carbohydrate

• nucleic acid

• protein

Which statement is not true about DNA and RNA?

• DNA contains thymine; RNA contains uracil.

• RNA is single stranded; DNA is double stranded.

• DNA uses ribose sugar; RNA uses deoxyribose sugar.

• RNA travels to the ribosome; DNA stays in the nucleus.

If one DNA strand reads TAC GGA TCA, the complementary DNA strand reads

• ATG CCT AGT

• AUG CCA UGA

• TAC GGA TCA

• ATG GGT TGA

RNA differs from DNA because RNA

• contains uracil

• is double stranded

• is made of amino acids

• never leaves the nucleus

If a DNA strand reads AAG TCG, the corresponding mRNA strand will read

• TTC AGC

• UUC AGC

• UUG TGC

• AAC TCG

The sugar found in RNA is

• deoxyribose

• glucose

• ribose

• sucrose

The sides (backbone) of the DNA molecule are made of

• sugars and phosphates

• amino acids

• nitrogen bases

• codons and anticodons
