DNA Review
name_______________________
1.
What does DNA code for?
2.
Where is l DNA kept and why?
3.
What are the three types of RNA? Describe each……..Physically and functionally.
4.
Draw the 4 DNA nucleotides and the 4 RNA nucleotides
.
5.
IF you are asked to transcribe a sequence of DNA, what do you do?
6.
Where does transcription take place?
7.
Transcribe this DNA: AAATTTCCCGGG
8.
What signals to the mRNA to start and stop building?
9.
IF you are asked to translate a sequence of DNA, what would you do?
10. Where does translation take place?
11. Translate this DNA: TTTCCCGGGAAAATACGC
12. What is the difference between a codon and an anticodon? What is the function of an anticodon?
13. Draw a piece of mRNA 5 codons long. Draw the pieces of tRNA that would match up.
14. Why is the genetic code considered universal?
15. Why do only a specific amino acid attach to each transfer RNA?
16. What units make up proteins and what type of bond is between them?
17. What are mutations and how do they affect traits?
18. Explain the types of mutation .
19. When are mutations “silent.”
20. What are some things that proteins do in your body? (name 4)
21. Where do the building blocks of nucleotides come from? Amino acids?
22. Explain how amino acid sequence affects the folding and therefore shape of a protein.
23. Do all of your cells contain the same DNA? If so, why do different cells behave differently or
produce different proteins?
24. MAKE SURE you can actually do transcription and translation and identify types of mutations in
a DNA sequence.
