Adenine: A
Thymine: T
Guanine: G
Cytosine: C
A pairs with T except in mRNA
In mRNA A pairs with U
But if there is a T in the code it translates to A
G always pairs with C
C always pairs with G
mRNA. tRNA
Adenine: Uracil. Thymine.
Thymine: Adenine. Adenine.
Guanine: Cytosine. Cytosine.
Cytosine: Guanine. Guanine.
2. Amino acids (I think)
3. Nucleus
4. Nucleus
5. Ribosomes (I think)
