|---|---|---|---|---|---|
| nucleotides | monomers made of phosphate, sugar and base to build the DNA molecule
🗑
|
||||
| replication | copying the DNA
🗑
|
||||
| DNA | blueprint for protiens needed for cell functions: made of genes
🗑
|
||||
| Deoxyribose | sugar molecule backbone of DNA molecule
🗑
|
||||
| Ribose | sugar backbone of RNA
🗑
|
||||
| phosphate group | phosphorus and oxygen molecule part of the nucleotide
🗑
|
||||
| nitrogen bases | 4 bases of DNA: thymine and adenine; cytosine and guanine
🗑
|
||||
| double helix | DNA structure like a twisted ladder
🗑
|
||||
| complementary bases | A & T; C & G
🗑
|
||||
| Interphase | Cell cycle phase of growth and preparation for division
🗑
|
||||
| M phase (mitosis and cytokinesis) | Cell cycle phase where the cell divides in two.
🗑
|
||||
| G1 | Interphase time of growth for the cell
🗑
|
||||
| S | Interphase time of DNA duplication
🗑
|
||||
| G2 | Interphase time of preparation for the cell to start dividing
🗑
|
||||
| Cell cycle | Life cycle of a cell from when it is formed, through interphase, mitosis and cytokinesis-- division into two new cells.
🗑
|
||||
| mitosis | The part of the cell cycle when the cell is going through the process of cell division
🗑
|
||||
| DNA (definition #2) | DeoxyriboNucleic Acid
🗑
|
||||
| monomer | smaller molecule parts that make up large molecules. For DNA, the small parts are the nucleotides
🗑
|
||||
| polymer | large molecules made up of smaller molecule parts. For DNA, the large molecule is DNA
🗑
|
||||
| daughter strands of DNA | new strands of DNA formed by connecting nucleotides to the parent strands
🗑

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.
