🗑
|
||||
| fertilization | process where a male gamete joins a female gamete to produce a new organism
🗑

| dominant | will be expressed when paired with a recessive gene
🗑
|
||||
| recessive | will only be expressed if paired with another recessive gene
🗑
|
||||
| Reasons to study DNA | help solve crime
helps doctors and scientists to treat diseases and illnesses

🗑
|

| location of DNA | located in the chromosomes inside the nucleus
🗑
|

| DNA | shaped like a double helix (twisted ladder)
unique to each person just like a fingerprint
genetic material of all living things
🗑
|
||||
| replication | process used when cells copy DNA
🗑
|
||||
| benefits of mutations | stronger animals
plants resistent to disease
cows producing more milk
larger fruit/vegetables

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.
