DNA & Cell Division
Quiz
Question | Answer |
---|---|
What does the model of DNA look like? | Twisted Ladder |
What enzyme proofreads and connects free nucleotides to the pre-existing old strand of DNA during replication? | DNA Polymerase |
What enzyme breaks the hydrogen bonds between the base pairs during DNA replication? | Helicase |
What molecule contains genetic information | DNA |
Where does DNA replication take place in eukaryotic cells? | Only in the nucleus |
DNA is an organic polymer composed of monomers called? | Nucleotides |
Cell spends most of its time in what phase? | Interphase |
During S Phase | The cell is replicating DNA for Mitosis |
Mitosis | Is the division of two newly formed Nuclei |
Interphase | Is the phase in which the cell splits into 2 new daughter cells. During this phase animal cells pinch off from the cleavage furrow and the emergence of the cell plate is discovered to be formed in plant cell. |
Why is DNA replication during Interphase important for the process of Mitosis? | The process ensures that each new daughter cell will receive the COMPLETE SET of genetically identical chromosomes as the original parent cell. |
Which example is representative of asexual reproduction through mitosis? | Bacteria, dividing itself in half to make two bacteria |
Eukaryotic, multicellular organisms go through mitosis when which type of cells are dividing? | Somatic Cells |
Which of the following does not occur during Interphase | The cell nuclear envelope disappears |
Cell division is controlled by | DNA |
