AP BIO Transcription/Translation CH 17 DUE 4/29/15

1. What is the Central Dogma of Molecular Biology?

2. List the similarities and differences between DNA molecules and nucleotides and RNA molecules and nucleotides.

3. Draw an RNA nucleotide. Draw a DNA molecule.

4. What are the three major types of RNA? What are the functions of each?

5. What is transcription and where does it occur?

6. What is translation and where does it occur?

7. What is the main enzyme that transcribes DNA into RNA?

8. How does RNA polymerase know where to start and stop?

9. Describe in detail how RNA is edited prior to leaving the nucleus (only in Eukaryotes).

10. What monomers make up polypeptide chains (proteins)?

11. The language of mRNA instructions is called the genetic code. This code is a chain of nucleotides. This code is read by ribosomes in 3 letter sequences called what?

12. What is the first amino acid laid down in every protein made in eukaryotes and the first codon?

13. Translation begins when the mRNA molecule in the cytoplasm attaches to a ribosome. This is called what?

14. The three bases on the tRNA molecule, called the _______________________, are complimentary to one of the mRNA codons.

15. Like an assembly line worker who attaches one part to another, the ribosome forms a peptide bond between the first and second amino acids. This is called what?

16. When the ribosome reaches a stop codon, it releases the newly formed polypeptide and the mRNA molecule, completing the process of translation. This is called what?

17. Below is a mRNA strand. Use this strand and the codon chart provided to make an amino acid chain and the DNA molecule that coded for the mRNA based on code contained in the mRNA strand.

DNA:

mRNA: UCGCACGGU

tRNA code:

Amino Acids:
