    1. organized in homologous pairs.
    2. circular.
    3. single-stranded.
    4. larger than that in chloroplasts.
    5. devoid of genes.
  3. Sexual exchange of DNA in Paramecia occurs through

    2. transformation.
    3. conformation.
    4. infection.
    5. conjugation.
  4. The origin of chloroplasts and mitochondria in eukaryote cells was probably due to
    1. conjugation.
    2. endosymbiosis.
    3. infection.
    4. paternal effect.
    5. heteroplasmy.
  5. Vertebrate mitochondria

    2. have ribosomes identical to cytoplasmic ribosomes.
    3. have ribosomes identical to yeast ribosomes.
    4. have ribosomes identical to protist ribosomes.
    5. have their own unique ribosomes.
