DNA/ Replication
Where is DNA found in eukaryotic (our) cells?
Nucleus
What is the cell checking for at the end of G2 check point?
DNA replication happen properly
A cat cell has 52 chromosomes (before S phase), after cell division how many chromosomes does each daughter cell have?
52 Chromosomes
In order to survive, cells want a high _____________ versus a low___________
Surface Area
Volume
What is the compliment to this DNA strand:
AATCGGAC
TTAGCCTG
Interphase is made up of what 3 phases?
G1, S, and G2
In what phase of mitosis do the chromosomes line up along the middle of the cell?
Metaphase
What/When are the three cell checkpoints? (draw cell cycle and make check points)
G1, G2, and M checkpoints
What is the name of the repeating units that make up DNA called? (these contain a nitrogen base, phosphate and a sugar group)
Nucleotide
What happens during the S phase of Interphase?
DNA Replication
In what phase of mitosis do identical chromosomes get pulled apart?
Anaphase
Describe what the cell is checking for during ONE of the cell checkpoints.
G1 = Growth
G2 = DNA is copied
M = Spindle Fibers attached
How many strands (sides) does the DNA double helix have?
2 complementary strands
A->T
G-> C
What happens during the G1 and G2 phases of Interphases?
Growth (and prep for cell division)
Put these phases in the correct order: Telophase, prophase, interphases, anaphase, metaphase, and cytokinesis
Interphase, prophase, metaphase, anaphase, telophase, cytokinesis (IPMATC)
If a cell fails any checkpoint, what will happen to the cell?
Apoptosis (cell suicide/death)
What is the end result of DNA Replication?
TWO IDENTICAL molecules of DNA
The division of the cytoplasm is called...
Cytokinesis
What is the end result of Cell Division?
TWO genetically IDENTICAL cells
What are the 4 purposes/functions of Cell Division (mitosis)?
GaRR
-Growth
-Asexual Reproduction
-Repair
-Replacement
