Where are proteins made?
On ribosomes in the cytoplasm.
300
Which allele decides the trait?
The dominant allele.

True or false: Meiosis produces 2 cells with the same genetic information
False! Mitosis produces 2 cells with the SAME information. Meiosis produces 4 cells with DIFFERENT genetic information.

What are the base pairing rules?
A pairs with T C pairs with G
400
What does changing the order of amino acids do?
Makes a different protein.

Describe how budding occurs.
A new, duplicate plant or animal begins to form on the parent. Grows until it is large enough to break off and live on its own.
