Quiz Answer Key and Fun Facts

1. Which of the following is found within mitochondria?

Answer: cristae

The Golgi apparatus packages the proteins. 'Patella' is the scientific name for kneecap.

2. OK, now for a dirty question: when two bacteria exchange genetic information with each other through direct contact, cell to cell, what is the process called?

Answer: conjugation

Transduction is when viruses introduce new genetic material to a bacterium; transformation is when the bacteria absorb outside genes. A euglena is a kind of one-celled organism.

Conjugation is facilitated by the formation of a bridge-type structure between the cells.

3. In DNA, adenine pairs with thymine. But in RNA, what replaces thymine?

Answer: uracil

The other nucleotides remain the same.

4. What on earth does a restriction enzyme do?

Answer: cuts DNA at specific sites

Geneticists use restriction enzymes to create recombinant DNA.

5. Mutations in which of the following kinds of genes causes cancer in humans (or so goes the current theory)?

Answer: proto-oncogenes

Carcinogens cause cancer, but they are not genetic -- instead, they're external factors like cigarettes. Gap genes are found in arthropods (like fruit flies); junk DNA is DNA that doesn't encode proteins, but scientists are finding that such DNA can still be fairly important. Proto-oncogenes, when acting normally, are important in regulating things like the growth of cells and their differentiation into tissue types -- but a mutation in a proto-oncogene turns it into an oncogene, and can lead it to transform its cell into a tumor cell.

6. What is the scientific name of the fruit fly, an organism much beloved by geneticists everywhere?

Answer: Drosophila melanogaster

7. Who used a flask with a curved neck to prove that spontaneous generation did not occur in a broth?

Answer: Pasteur

Redi and Spallanzani used other experiments to disprove the theory of spontaneous generation.

8. What does 'DNA' stand for?

Answer: deoxyribonucleic acid

RNA, meanwhile, is simply ribonucleic acid. The base sugar of RNA is ribose, while the base sugar of DNA is deoxyribose.

9. What human organ stores concentrated bile, which is needed to digest lipids (including fats)?

Answer: gall bladder

The liver secretes bile, which is collected and concentrated in the gall bladder.

10. The process of converting a DNA sequence to an mRNA message is called transcription. What is the process of converting an mRNA molecule to a protein (through the mediation of tRNA) called?

Answer: translation

One way to remember the difference between translation and transcription is that transcription is in the same language -- that of nucleotides, common to both RNA and DNA -- while translation is between languages (the nucleotides of RNA and the amino acids that make up proteins).
