| GENE | A SECTION OF DNA THAT CONTAINS THE CODE FOR A PARTICULAR PROTEIN. |
| CHROMOSOME | COMPOSED OF ONE DNA MOLECULE & SOME PROTEINS. |
| CHROMATIN | AN UNCOILED CHROMOSOME. |
| CHROMATID | ONE OF THE TWO STRANDS OF A CHROMOSOME OR A CHROMATIN. |
| CENTROMERE | PLACE WHERE TWO CHROMATIDS ARE ATTACHED. |
| INTERPHASE & CELL DIVISION | TWO MAIN STAGES OF THE CELL CYCLE. |
| MITOSIS & CYTOKINESIS | TWO MAIN STAGES OF CELL DIVISION. |
| INTERPHASE | THE STAGE WHEN THE CELL GETS READY FOR MITOSIS. |
| PROPHASE | THE LONGEST PHASE OF MITOSIS. |
| METAPHASE | PHASE WHEN CHROMOSOMES LINE UP IN THE MIDDLE OF THE CELL. |
| ANAPHASE | CHROMATIDS MOVE TOWARD THE OPPOSITE ENDS OF THE CELL. |
| TELOPHASE | TWO NUCLEI FORM DURING THIS PHASE. |
| WHY IS MITOSIS IMPORTANT? | IT PRODUCES TWO NUCLEI WITH THE SAME NUMBER AND KINDS OF CHROMOSOMES AS THE PARENT CELL. |
| DNA REPLICATION | A DNA MOLECULE FORMS AN IDENTICAL COPY OF ITSELF. |
| WHAT IS THE LONGEST PHASE OF THE CELL CYCLE? | INTERPHASE |
| CYTOKINESIS | DIVISION OF THE CYTOPLASM |
| MITOSIS | DIVISION OF THE NUCLEUS. |
| WHICH PHASE OF MITOSIS IS THE OPPOSITE OF PROPHASE? | TELOPHASE |
| WHAT STRUCTURE IS PRESENT IN ANIMAL MITOSIS BUT ABSENT IN PLANT MITOSIS? | CENTRIOLE |
| WHAT STRUCTURE IS PRESENT IN PLANT CYTOKINESIS BUT ABSENT IN ANIMAL CYTOKINESIS? | CELL PLATE |
| WHEN ARE CHROMOSOMES DOUBLE-STRANDED? | PROPHASE & METAPHASE |
| WHEN ARE CHROMOSOMES SINGLE-STRANDED? | ANAPHASE & TELOPHASE |
