Mutations
Yoon
| Term | Definition |
|---|---|
| What changes in the protein when the a mutation occurs outside of the encoded part of mRNA? | Nothing changes, because the mutation isnt being coded. |
| 2.What amino acid sequence is present in the DNA sequence, GTACAGAGTAATCAAA? | His Val Ser Leu Val |
| What are some mutagens that could cause DNA to change? | BPA, Abren, and Butonate |
| Which is usually disrupts encoded proteins: frameshift mutations or point mutations? | Frameshift mutations |
| What are some ways DNA mutations can effect proteins? | If there is a substitute frameshift mutation, there may be no start codon or stop codon. |
| What are some factors that can cause genetic mutations? | Mutagens and parents consumed were around any mutagens that could affect you during pregnancy,etc.Also sunlight, radiation, smoking. Endogenous:errors during DNA replication can lead to genetic changes and toxic products of cellular metabolism. |
| What changes in the DNA cause point mutations to occur? | The start codons and stop codons |
| What changes in the DNA cause frameshift mutations to occur? | When is being added or deleted |
| What changes in the DNA are harmless to the encoded protein? | The change in amino acids |
| What changes in the DNA cause point mutations to occur? | substitution |
| In Question #2, if the red G was substituted with an A, how would that change the encoded amino acid sequence? | The sequence would be Met, Lys, His, STOP |
| In Question #2, if the blue A was substituted with a T, how would that change the encoded amino acid sequence? | The sequence would be Met, Ser, His, STOP |
| In Question #2, if the red G was deleted from the DNA, how would that change the encoded amino acid sequence? | The sequence would be Met, Ser, His, STOP |
| In Question #2, if the blue A was substituted with a T, how would that change the encoded amino acid sequence? | The sequence would be Met, Ser, His, STOP |
| Which of the mutations in #8-10 would be the most harmful? Why do you say so? Which would be the least harmful? Why do you say so? | It would be harmful if the red G were to be deleted from the sequence because there is no stop codon, it would keep on going. |
