B) protein; DNA; RNA

C) DNA; mRNA; tRNA

D) DNA; RNA; protein

The enzyme(s) that catalyze(s) the synthesis of RNA is (are)

A) RNA polymerase

B) tRNA synthetase

C) ribosomal RNA

D) all of these are correct

Model eukaryotic organisms such as stickleback fish have helped biologists understand

A) genes involved in development

B) the ways in which genes are expressed

C) genes encoding proteins that are essential for all cells

D) All of these are correct

Viruses consist of

A) a nucleic acid core and a protein capsid.

B) a cell wall surrounding nucleic acid.

C) RNA and DNA enclosed in a membrane.

D) a protein core surrounded by a nucleic acid capsid.

An operon

A) is regulated by a repressor binding at the promoter.

B) has structural genes that are all transcribed from same promoter.

C) has several promoters, but all of the structural genes are related biochemically.

D) is a set of structural genes all under the same translational regulation.

Eukaryotic chromosomes

A) are circular and contain origins and terminator sequences.

B) are linear and have origins and telomeres.

C) contain coding and noncoding sequences.

D) Both B and C.

DNA fragments are separated using gel electrophoresis

A) because DNA is pulled through the gel toward the negative end of the field.

B) because larger DNA fragments move faster through the gel than smaller DNA fragments.

C) to identify and isolate DNA fragments.

D) to synthesize DNA for cloning.

Complementary base pairing is important for

A) ligation reactions with blunt-end DNA molecules.

B) synthesizing DNA molecules from mRNA templates.

C) restriction endonucleases to cut cell walls.

D) hybridization between DNA and transcription factors.

The transcription complex includes _______ and _______.

A) transcription factors; promoters

B) regulator proteins; regulators

C) anticodons; polypeptide chains

D) Both A and B.

DNA fingerprinting works because

A) genes containing the same alleles make it simple to compare different individuals.

B) PCR allows amplification of proteins from single cells.

C) there are multiple alleles for some DNA sequences, making it possible to obtain unique patterns for each individual.

D) DNA in the skin cells is very diverse.
