In the nucleus
A codon is a sequence of how many bases?
3 bases
The building blocks of DNA and RNA are
nucleotides
What is a gene mutation?
any change in DNA's code
What is the shape difference in DNA and mRNA?
DNA is a double Helix, RNA is a single stranded or helix.
What anticodons mRNA bases would pair with DNA in this strand
(G-G-A-T-C)?
C-C-U-A-G
Translation takes place at which organelle?
ribosome
What is the difference between an amino acid and a protein?
Amino acids are the building blocks of a protein. A protein is a chain of amino acids that are connected to each other.
What is a chromosome mutation?
any change in chromosome structure or number
