3. CEen celmembraan
4. DRibosomen

What is a eukaryote?

1. AAn organism whose cells have a nucleus
2. BAn organism that lives only in extreme heat
3. CAn organism made of a single cell without a nucleus
4. DA virus that infects animal cells

What is cytokinesis?

1. AThe pairing of homologous chromosomes
2. BThe copying of DNA before division
3. CThe condensing of chromosomes in prophase
4. DThe division of the cytoplasm into two cells

Why are G–C base pairs held together more strongly than A–T pairs?

1. AG–C pairs form three hydrogen bonds, and A–T pairs form two
2. BG and C are both purines, so they fit more tightly
3. CG–C pairs are joined by strong covalent bonds instead of hydrogen bonds
4. DA–T pairs are found only in RNA

A deletion removes exactly three bases, forming one whole codon, from the middle of a gene. What is the most likely result?

1. AThe protein lacks one amino acid but the rest is unchanged
2. BThe protein becomes three times longer
3. CEvery amino acid after the deletion is changed to a new one
4. DNo protein can be made at all

Which stage of aerobic respiration produces the most ATP?

1. AGlycolysis in the cytoplasm
2. BThe electron transport chain
3. CThe Krebs cycle in the matrix
4. DFermentation

The antibiotic tetracycline binds to bacterial ribosomes. Which process does it block, and why are human cells much less affected?

1. ADNA replication, because bacteria have no DNA polymerase
2. BTranslation, because human cells have no ribosomes
3. CTranslation, because bacterial ribosomes differ from human ribosomes
4. DTranscription, because human cells have no RNA polymerase of their own
