Quiz Answer Key and Fun Facts

1. What does RNA stand for?

Answer: Ribonucleic Acid

Ribonucleic acid is abbreviated RNA, just as deoxyribonucleic acid is DNA.

2. In RNA, to which base does adenine bond?

Answer: Uracil

In DNA, adenine bonds to thymine, but in RNA, adenine bonds to uracil. Thymine is not found in RNA. Guanine and cytosine always bond to each other in DNA and RNA.

3. Friedrich Miescher was an early pioneer in RNA, finding nucleic acids in 1868. Which country was he from?

Answer: Switzerland

Miescher was born in Basel, and worked primarily at the University of Tubingen in Germany, where he made his breakthrough.

4. In tRNA, what does the letter "t" stand for?

Answer: Transfer

Transfer-RNA transfers an amino acid to the ribosome during protein synthesis.

5. What does the "m" in mRNA stand for?

Answer: Messenger

Messenger-RNA carries the DNA code in the form of a molecular message from the nucleus to the ribosome in the cytoplasm.

6. What is the process of creating mRNA from DNA called?

Answer: Transcription

The re-writing or transcribing of the DNA code to RNA is called transcription.

7. Where does transcription occur?

Answer: In the nucleus

The transcribing of DNA to RNA occurs in the nucleus, since that is the only place where the DNA is found.

8. On what organelle in the cell does protein synthesis occur?

Answer: Ribosome

Ribosomes are created in the nucleolus, and DNA is copied to RNA in the nucleus, but the code is made into a protein chain at the ribosome in the cytoplasm.

9. What is the term for a 3-nucleotide sequence on mRNA that codes for an amino acid?

Answer: Codon

A codon is a sequence of 3 nucleotides on mRNA that codes for an amino acid. Anticodons, complements of mRNA, are found on the tRNA, active sites are found in enzymes, and triple salchows are found in figure skating.

10. What is the term for a group of ribosomes on one mRNA chain?

Answer: Polysome

Polysomes are groups of ribosomes each creating a polypeptide chain from the same mRNA strand. Lysosomes are organelles containing digestive enzymes in a cell, chromosomes are long coiled strands of DNA, and polypeptides are chains of amino acids.
