What is...
What are the FOUR letters that represent the DNA bases?
A, T, C, and G
Who is the father of genetics and what did he study?
Gregor Mendel
His pea plants!
Please define heredity
The passing of traits from parent to offspring
Where is your DNA located in your cells?
The nucleus
What is the trick to help you remember the four DNA bases?
Apple in the Tree, Car in the Garage!
What is an allele?
A form/variation of a gene
How a trait PHysically appears is called it's...
PHenotype!
Please define genetics
The STUDY of passing traits from parents to offspring
What shape is your DNA?
Double helix!
How many chromosomes do humans have?
46
What is genetic code?
Instructions in the DNA that tell the cell what to become
The internal genetic structure that we can't see (this is determined by the two letters in our Punnett Squares!!) is called an organism's...
Define coding
Giving instructions
DAILY DOUBLE!!!!!! GET THIS RIGHT AND YOU GET DOUBLE POINTS!!!!!!!!
How do you receive your DNA from your mother and father?
What is an example of a trait?
Skin color, eye color, hair color, hair type, freckles, dimples, etc.
What is a chromosome?
A threadlike structure of DNA wrapped around a protein structure
Your cells contain chromosomes from both
parents
Define gene
A chunk/portion/section of your DNA
What does your DNA code for?
Your traits!
True or False? Genes alone are the ONLY thing that can affect your phenotype.
FALSE! Your environment can affect your phenotype.
What is polygenic inheritance?
When multiple genes determine the phenotype of a trait.
DAILY DOUBLE!!!!!!! IF YOU GET ALL ANSWERS CORRECT YOU GET DOUBLE POINTS!!!!!!!!!!!!!!!!
Why did Greg choose to use pea plants?
- They reproduce quickly
- They have easily observed traits
- They can easily control which ones reproduce
Define trait
A characteristic about you that was given to you genetically from your ancestors
What pairs our DNA bases together?
Hydrogen bonds!
Different arrangement of DNA bases are what make you...
YOU!
