What are 3 types of RNA?
mRNA, tRNA and rRNA
200
What is the structure difference in DNA and mRNA?
DNA is a double Helix, RNA is a single Helix.

What mRNA bases would pair with this strand of DNA: G-G-A-T-C-G-C-C-T-A
C-C-U-A-G-C-G-G-A-U
200
What occurs during translation?
an mRNA strand is "decoded" into a sequence of amino acids, that result in a protein
200
What is the relationship between amino acids and proteins?
200
What is important about these three codons: UGA, UAA, and UAG?
They are "stop" codons and they signal that the protein is done being assembled.
