The cell Cycle pt. 1
the cell cycle creates 2 identical ______.
cells
The purpose of the cell cycle is for ______ & _______
Growth & Repair
True or False: The DNA of the cell is condensed into chromosomes at the start of Mitosis
True
________ is the genetic material that serves as the cell's instruction manual.
DNA
In what organelle does photosynthesis take place?
Chloroplast
What occurs during Gap 2 of the cell cycle
The cell continues to grow and prepares to divide
In humans, what type of cells are stuck in G0?
Neurons (Brain cells)
What happens during Cytokinesis
The cell membrane pinches off and creates 2 daughter cells
______ are segments of DNA
Genes
What is are the inputs of cellular respiration. Be sure to include the correct amouonts
6 oxygen and 1 glucose molecule
What occurs during S phase?
DNA replication
What occurs during G1 of the cell cycle?
the cell Grows. Extra proteins and organelles are made
Draw a picture of a parent cell and what the daughter cells will look like after going through the cell cycle
parent and daughter cells should look exactly the same
Nucleotide
True of False: Mutations can only occur while the DNA is being replicated?
False. Mutations can happen at anytime
What is the longest part of interphase
G1
What type of disease occurs if the cell cycle checkpoints no longer work?
Cancer: uncontrolled cell division.
A parent cell has 15 chromosomes. After going through mitosis, daughter cells are created. How many chromosomes will each daughter cell have?
15. Daughter cells and Parent cells are exactly the same.
What is the difference between a Chromosome and a gene?
A chromosome is tightly packaged DNA and a gene is only a segment of that DNA
Bacteria reproduce using what type of reproduction
Asexual reproduction (Binary Fission)
On your white board, draw/ describe what a cell would look like if it skipped interphase and went straight to Mitosis. (must have at least 2 things)
The DNA would not be copied so each cell would not have the exact same DNA
The cell would not have grown so it would be smaller than usual
The Organelles would not have replicated so the Cell would have less organelles than usual.
Down Syndrome is a genetic disease. What type of cells do doctors need to collect in order diagnose someone with Down Syndrome?
Any cell in the body because all cells in an individual's body have the the same DNA
What is a stem cell and why are they unique?
Stem cells are cells that can differentiate into other types of specialized cells once they turn certain genes on/off
Describe the complementary base-pair rule of DNA
A binds with T
C binds with G
What causes your heart cell to look and act differently than your skin cell?
Different parts of the DNA (genes) are read in different types of cells. Heart cells do not read the same genes as skin cells.
