|---|---|---|---|---|---|
| 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.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
