"What is DNA?"
1) In what organelle would I find your DNA? In the nucleus
2) What does DNA stand for? DeoxyriboNucleic Acid
3)The DNA molecule comes in the form of a twisting ladder and scientists call its shape a double helix
4) The MIDDLE of the DNA MOLECULE is made of bases. These bases will only pair up in a particular way:
A always pairs with T
C always pairs with G
5) What makes up the handrails or SIDES of a DNA molecule Sugar and
6) G stands for Guanine
A stands for Adenine
T stands for Thymine
C stands for Cytosine
"What is a Gene?"
1) GENES are instruction manuals for our bodies
2) GENES are made of DNA
3) A gene or protein called blood is responsible for our RED BLOOD CELLS to carry oxygen
4) If our hemoglobin gene is normal, the hemoglobin protein will for fine. But if the instructions in the gene are changed, or "mutated" changes in the hemoglobin could result in the disorder sickle cell anemia
5) True or false: Your DNA or GENES are responsible for your eye color? TRUE
"What is a chromosome?"
1) If you pulled DNA from your cells it would be how long? 3 meters
2) How does all of that DNA fit inside your cells? The DNA is packaged into chromosomes
3) Chromosomes are storage units for DNA
4) True or False: Different organisms have a different number of chromosomes inside each cell? TRUE
5) How many chromosomes do humans have? 46 chromosomes
6) You received 23 of your chromosomes from your mom and 23 from your dad.
7) Males have x and y sex chromosomes. Females have 2 x sex chromosomes.
8) How many chromosomes does a mosquito have? 6
How many chromosomes does a onion have? 16
How many chromosomes does a carp have? 104
PART TWO:
DNA Replication
1) DNA, the molecule that holds genetic information, makes an exact copy of itself whenever it divides.
2) Where are you located? In the nucleus. Draw a picture that is labeled where you're located.
3) What is the first step of DNA replication?
4) Where does the DNA molecule unzip?
5) A always goes with T
C always goes with G
