In which specimen were cells first identified?

• cork bark

• nucleus

• mitochondrion

• DNA

Which best describes mitochondrial DNA (mtDNA)?

• Mitochondrial DNA requires large amounts for testing.

• Mitochondrial DNA is the same as nuclear DNA.

• Mitochondrial DNA can be traced for generations.

• Mitochondrial DNA is inherited through the father.

A student wonders whether removing the nucleus from a cell would result in a new prokaryotic cell. Why would this procedure fail to produce a prokaryotic cell?

• The cell would lack the structure that is needed to produce proteins.

• The cell would lack the structure that is needed to protect the cell’s organelles.

• The cell would lack control over materials that move into and out of the cell.

• The cell would lack genetic information.

Which statement is least likely to support the endosymbiotic theory?

• Mitochondria and chloroplasts are much larger than prokaryotic cells.

• Mitochondria and chloroplasts have DNA that resembles bacterial DNA.

• Mitochondria and chloroplasts contain their own ribosomes.

• Mitochondria and chloroplasts reproduce independently from the cell.

Which discovery supported the endosymbiotic theory?

• DNA in the cell nucleus

• DNA in mitochondria

• DNA in the cytoplasm

• DNA in ribosomes
