Bio Unit 3 vocab
Cell cycle and DNA
| Term | Definition |
|---|---|
| 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 |
