2nd 9 Weeks Test
Nine Weeks Test Review
| Term | Definition |
|---|---|
| Cancer | Uncontrolled cell growth that disrupts the cell cycle. |
| Cell Cycle | Interphase, Mitosis, Cytokinesis (IPMATC) |
| Mitosis | Part of cell division with PMAT. |
| Daughter Cells | The resulting cells of the cell cycle. |
| Genetic Material | DNA or RNA. The sequence of nitrogen bases (or nucleotides) is responsible for traits and the genetic code. |
| S Phase | The second part of Interphase where DNA is replicated. |
| M Phase | Mitosis- where the nucleus divides. |
| DNA Replication | When DNA makes identical copies for each new cell to have. |
| Nuclear Division | Splitting of the nucleus. |
| DNA | Molecule that codes for proteins, which are necessary for every day functions of an organism. |
| Cytokinesis | Division of the cytoplasm and result is two cells. |
| Carbohydrate | Provides structure to a DNA molecule. It is part of the sugar-phosphate backbone. |
| Transcription | Transcribing DNA into mRNA. Two strands (DNA) to one strand (RNA). |
| mRNA | mRNA is used to find the amino acid chain. |
| Polypeptide | A short chain of amino acids. |
| Mutation | A random change in DNA. |
| Somatic Cell | Body cells. Do not pass on mutations to offspring. |
| Gamete | Sex or reproductive cells. Ex: egg and sperm. Can pass mutations to offspring. |
| Substitution Mutation | Replacing one nitrogen base with another. |
| Insertion Mutation | Adding extra nitrogen base(s). |
| Translocation Mutation | Moving nitrogen bases to a different location in the sequence. |
| Deletion Mutation | Removing a nitrogen base(s) from a sequence of DNA. |
| Allele | One version of a trait. A or a |
| Heterozygous | Different versions of an allele. Aa |
| Homozygous | Same versions of an allele. aa |
| Crossing Over | Gametes will contain new allele combinations. This leads to genetic variation. |
| Genotype | The genetic makeup of an organism. TT, Tt, or tt |
| Phenotype | The observable physical characteristics of an organism. Tall or short |
| Dominant | Always shows up. TT or Tt |
| Recessive | Only shows up if two are present. tt |
| Gene | A section of DNA that codes for a trait. |
| Complementary DNA | The DNA bases that pair with each other. A-T, G-C. |
| G1, S, G2 | Parts of Interphase where cells grow, replicate DNA, and a checkpoint before entering mitosis. G2 ensures healthy, undamaged daughter cells are made. |
