🗑
|
||||
| Thymine | A nitrogen base (pyrimidine) that bonds with Adenine
🗑
|

| Guanine | A nitrogen base (purine) that bonds with Cytosine
🗑
|
||||
| Cytosine | A nitrogen base (pyrimidine) that bonds with Guanine
🗑
|
||||
| Deoxyribose sugar | The sugar found in a nucleotide of DNA. (The D in DNA stands for deoxyribose)
🗑
|
||||
| carbohydrate ring | The sugar ring found in a nucleotide (AKA Deoxyribose sugar)
🗑
|
||||
| Double Helix | The model that shows the structure of a DNA molecule. Two strands wind around one another.
🗑

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.
