Review: DNA, The Cell Cycle and Cancer

Match the term with the description. Interphase The parent cell. DNA in the form of chromatin. Cell grows and DNA is copied. Prophase The nuclear membrane disappears. The spindle and centrioles appear. DNA in the form of chromosomes. Metaphase Chromatids line up along the equator. Anaphase The sister chromatids are separated to poles. Telophase A nuclear membrane forms around the chromosomes. Cell plate forms in plant cell division. Animal cells form a cell furrow. Cytokinesis Division of the Cytoplasm. Two daughter cells formed. What is the end product of mitosis? 4 daughter cells 4 gametes 2 daughter cells 2 gametes Match the term with the description. Chromatin Loosely packed DNA Chromosome Tightly packed strands of DNA Chromatid Single strands of duplicated chromosomes What is the correct order of the cell cycle? G1 --> M --> G2 ---> S --> C G1 --> S --> G2 ---> M --> C G1 --> C--> G2 ---> S --> M G1 --> M --> S---> G2 --> C What is the longest phase of the cell cycle? Cytokinesis Mitosis Metaphase Interphase A Great White Shark has 82 chromosomes. When its cells undergo mitosis, how many daughter cells are made? 1 2 4 A Great White Shark has 82 chromosomes. How many chromosomes will the daughter cell have? 82 41 164 How are complex organisms organized? Organism --> organ system --> tissues --> cells --> macromolecules Cells--> macromolecules --> tissues--> organism --> organ system Organism --> organ system --> tissues --> macromolecules--> cells Macromolecules --> cells --> tissues--> organ system --> organism Match the phase of cell division with its image Prophase Telophase Anaphase Metaphase Cytokinesis What structure holds chromatids together? Centromere Centriole Cytoplasm In animal cells, what structure pulls chromatids apart during mitosis? Centromeres Centrioles Cytoplasm What is the name of programmed cell death? Apoptosis Spindle Fiber Cleavage Furrow Kinases As an embryo develops cells become adapted to specific tasks like muscle cells, bone cells, and nerve cells. What is this process called? Apotosis Hybridization Hypertonic Differentiation Which type of tumor travels through the body? Malignant Benign Beneficial The nitrogen bases of DNA ALWAYS pair up the same way. Match the correct bases together. Adenine (A) Thymine (T) Cytosine (C) Guanine (G) Match the parts to the image: A adenine T thymine C Cytosine G guanine X Deoxyriobose Sugar Y Nitrogen Bases W Phosphate In DNA replication, the term SEMI-CONSERVATIVE means... DNA can be unzipped and not destroyed Only four letters are needed for DNA to replicate it produces two copies that each contained one of the original strands and one new strand In which of the following phases of the cell cycle is DNA replicated? G2 of interphase G1 of interphase S of interphase Mitosis cytokinesis What is the gray blob in this gif representing? DNA ligase enzymes glueing in free nucleotides Thymine nucleotides bonding with Adenine nucleotides Helicase enzymes unzipping and unwinding the DNA double helix DNA polymerase enzymes forming hydrogen bonds to recreate the double helix shape
