The Cell Cycle Foldable 10-28-2016 Pick up handout! • New unit, new vocabulary!!! • Copy down vocabulary words on page 25 of notebook • • • • • • Anaphase Cytokinesis Interphase Transcription Cell cycle Daughter cell M phase Deoxyribonucleic Acid (DNA) Centriole Diploid Metaphase Centromere DNA replication Mitosis Chromatid G1 phase Prophase Chromosome G2 phase S phase The Cell Cycle Foldable • Today we will go over the cell cycle by creating a foldable • Take your handout and fold it in half so that it looks like this cytokinesis M i t o s i s I n t e r p h a s e The Cell Cycle The cell cycle • The life of a cell • The alteration between dividing and not dividing The cell cycle Interphase • The nondividing part of the cell cycle • The nuclear membrane is intact throughout interphase • Split into 3 phases • G1 phase, S phase, and G2 phase G1 Phase • Typically the longest phase of the entire cell cycle • The cell grows and produces cell components • The DNA is loosely spread out, and you can’t see individual chromosomes (chromatin form) S Phase • DNA is replicated • Every DNA molecule is copied exactly, forming 2 sister chromatids that stay attached to each other G2 Phase • Cell prepares for division • Makes the cytoskeleton proteins it needs to move the chromosomes around Mitosis • Division of genetic material and nucleus of the cell leading up to cell division Prophase • DNA appears as chromatin coils that pair up as they condense. • Nuclear membrane disappears Metaphase • Chromatid pairs line up along the middle of the cell • Centrioles form spindle fibers attaching the chromatid pairs at their centromeres Anaphase • Chromatid pairs separate and are pulled towards the cells poles by the spindle fibers Telophase • Cells get ready to divide into two by forming new nuclear membranes around the separated sets of chromosomes Cytokinesis • After mitosis ends • Cytoplasm and organelles of the cell divide forming two identical cells
