DNA, protein synthesis, mutations

RNA contains the nucleic acids:

• Thymine, Guanine, Cytosine, Adenine

• Thymine, Guanine, Cytosine, Uracil

Write the complementary DNA strand for the following:

GCC-ATC-ATA

Can you have a mutation on a gene, but still make the normal protein for that gene?

• No, all mutations are bad

• Yes, mutations do not change the amino acids and so the proteins are not affected

• Yes, not all mutations change the amino acid sequence (proteins can be normal)

• No, all mutations stop amino acids from being put together.
