A Cell Spends more time in this phase than in any other. Name this cell cycle stage:
Interphase
What are the 2 main phases of the cell cycle?
Interphase and Mitosis
This phase occurs before DNA replication.
G1 phase
Which phase does DNA replication occur during?
Synthesis (S) phase
Which stage of Mitosis is characterized by DNA coiling up into chromosomes?
Prophase
In which stage of Mitosis does the nuclear envelope dissolve, and spindle fibers form?
Prophase
Which Mitosis phase is characterized by sister chromatids lining up at the cells equator?
Metaphase
Which stage of Mitosis follows Anaphase?
Telophase
Which phase of Interphase double checks for errors in the DNA?
G2 Phase
Which phase of Interphase is characterized by preparation for the nucleus to divide?
G2 Phase
What is the corresponding base to Adenine?
Thymine
During DNA replication, the DNA unzips down the middle, breaking this type of bond between nucleotides:
Hydrogen Bonds
Which phase of Mitosis do chromosomes unravel, and nuclear envelopes reform?
Telophase
Which Mitosis phase is characterized by sister chromatids separating and individual chromosomes moving to the poles of the cell?
Anaphase
What is the final stage of cell division?
Cytokinesis
What is the name of the fragments of DNA that the Lagging Strand produces during replication?
Which strand of DNA begins with the 5' end and is able to be replicated uninterrupted?
The Leading Strand
This stage of the cell cycle is characterized by normal functions such as synthesis of proteins, growth and preparation for cell division.
Interphase
Which stage of Mitosis does the Cell have 2 nuclei?
Telophase
During DNA replication, the DNA produces 2 complete strands of DNA. This DNA is composed of 1 strand of the original DNA, and 1 strand of newly assembled DNA. Such a process is known as:
Semiconservative
The structure that holds the 2 identical chromosomes together during Mitosis.
Centromere
The 4 possible bases that compose the "rungs" on the ladder of DNA
Adenine, Thymine, Cytosine, Guanine
What organelle produces spindle fibers?
Centrioles
The package that DNA is tightly coiled into in order to aid cell division.
Chromosomes
Deoxyribose
