Question 1: Single-stranded ________ can also be detected, since it usually folds back onto itself and thus provides local base pairing for the dye to intercalate.
Non-coding RNARNADNASmall interfering RNA

Question 2:
What is the chemical name of Ethidium bromide (IUPAC)
3,8-Diamino-5-ethyl-6-phenylphenanthridinium bromide
3-Hydroxy-4-oxo-4H-pyran-2,6-dicarboxylic acid
Pentyl butanoate
-4,7-dimethyl-1--n1,2,4a,5,6,8a-hexahydronaphthalene

Question 3: By moving into this ________ environment and away from the solvent, the ethidium cation is forced to shed any water molecules that were associated with it.
SuperhydrophobeHydrophileHydrophobeChemical polarity

Question 4: In the case of ________ this is usually double-stranded DNA from PCRs, restriction digests, etc.
ProteinDNAGeneRNA

Question 5: When exposed to ultraviolet light, it will fluoresce with an orange colour, intensifying almost 20-fold after binding to ________.
DNAGeneRNAProtein

Question 6: Ethidium bromide may be a mutagen, ________ or teratogen although this depends on the organism and conditions employed.
CarcinogenCarcinogenesisCancerNeoplasm
