Tic Tac Toe TEAM 2
1. Where does translation take place?
(ribosome)
2. Where are anticodons found, and what is their purpose? (at the bottom of a tRNA, to base pair with codons to
ensure the correct amino acid is being delivered to the ribosome)
3. What type of mutation is caused by adding or deleting a nucleotide from a sequence?
(Frameshift mutation)
4. Guanine always binds with ____?
(Cytosine)
5. Which amino acid corresponds with the start codon?
(Methionine)
6. In DNA, Thymine binds with _____?
(Adenine)
7. Why are frameshift mutations worse than point? (Because it disrupts more than just one amino acid)
8. If 30% of your DNA is Guanine…..what percentage will be Adenine?
(20%.....explanation: if Guanine is 30%, so should Cytosine since they bond together….that leaves 40% for
Adenine and Thymine, half of 40 is 20.)
9. Where is DNA found in a eukaryotic cell?
(Nucleus)
10. What happens at the end of translation?
(a stop codon is reached)
11. How can mutations be passed to offspring?
(only if the mutation is in the sex cell)
12. Why are codons important to protein synthesis?
(they are the codes brought to the ribosome on mRNA, and they each code for a specific amino acid)
13. What decides what kind of protein is going to be made?
(the sequence of nucleotides….different sequences make different proteins)
14. In what instance would a mutation not matter or cause no affect?
(if the codon ends up coding for the same amino acid)
15. What happens to the DNA molecule at the end of transcription? (It zips back up and re-coils)
16. Why do biologists believe that all living things are related? (we all use the same genetic code/ all codons in each
organism code for the same amino acids)
17. What two processes that involve DNA occur in the nucleus?
(Replication and Transcription)
18. What type of bonds are between the sugar and phosphate in a nucleic acid?
(strong covalent)
19. Why is mRNA important in protein synthesis? (it carries the genetic code from the nucleus to the ribosome)
20. What is responsible for proofreading your DNA and RNA to find problems?
(enzymes)
