|---|---|---|---|---|---|
| *mutation* | changes in DNA sequences; change in sequence of nucleotides
🗑
|
||||
| recombination | change in the positioning of the genetic material
🗑
|
||||
| Two ways that cause mutation | errors in DNA replication (mispairing of bases by DNA polymerase) and mutagens (agents that damage DNA)
🗑
|
||||
| missense | genetic mutation - codon for one amino acid is changed to one that codes for another
🗑
|
||||
| frameshifts | changes the reading frame of genetic message
🗑

| can radiation cause mutation? | yes
🗑
|
||||
| how is thymine dimers made? | are made when UV light crosslinks adjacent bases
🗑
|
||||
| carcinogens | agents that cause cancer
🗑
|
||||
| p53 | check point guard (if cell is damage, p53 says stop to damage cell and go fix your DNA, induce repair enzyme)
🗑
|
||||
| Kinds of mutation | deletion, duplication, inversion, reciprocal translocation
🗑
|
||||
| reciprocal translocation | cross over between non-homologs
🗑
|
||||
| inversion | region on chromosome are switched
🗑
|
||||
| Give an example of disorder of chromosomal translocation | chronic myelogenous leukemia (CML)
🗑
|
||||
| true or false? | cancer cells have many translocation mutation?
🗑
|
||||
| Are mutation always bad? | they are the bases for evolution
🗑

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.
