DNA Replication
Do you really know mitosis?
100
This process is where the chromosomes are lined up in the middle of the cell.
Metaphase
100
What process is this?
Anaphase
100
What is the shape of DNA?
Double Helix
100
What does helicase do in DNA replication?
Unzips the DNA
100
What are the organelles called that extend the spindle fibers?
Centrioles
200
This process is where the sister chromatids are pulled away from one another.
Anaphase
200
What process is this?
Telophase
200
What is uncondensed, stingy DNA called?
Chromatin
200
Describe what happens during the building and extending part of DNA replication.
DNA polymerase adds nitrogenous bases to build a new strand of DNA.
200
What is the division of the cytoplasm called?
Cytokinesis
300
This process is where the cell begins to cleave and the nucleus begins to develop.
Telophase
300
What process is being shown?
Prophase
300
Tightly packed DNA is called what?
Chromosomes
300
What does ligase do in DNA replication?
Glues everything together.
300
What is the name of the structure that connects the two sister chromatids together?
Centromere
400
This process is where the nucleus dissolves and spindle fibers grab onto the chromosomes.
Prophase
400
What process is this?
Metaphase
400
Which of the following is not a structure of DNA?
1. Nitrogenous base
2. Phosphase Group
3. Oxygen
3. Oxygen
400
In DNA replication, if the code CCT is read, what should the complimentary base pairs read?
GGA
400
What nitrogenous base pairs with THYAMINE
Adenine
500
This is the longest part of cell division. It is where the cell grows, replicates its DNA, and finally grows some more.
Interphase
500
What process it this?
Interphase
500
What holds the nitrogenous base pairs together?
Hydrogen bond
500
True or False:
At the end of DNA replication, one strand of DNA has both original strands, and the other has both new strands.
False
Extra 200 points if you can tell me why it is false.
500
Why do we need cell division?
Creates new cells
