What determines the shape and function of a protein?

• The sequence of amino acids

• The type of ribosome that assembles the protein

• The cell that manufactures the protein

How can a mutation in the DNA sequence result in NO change to the protein that is made?

• There are multiple codons that can code for the same amino acid and result in the same protein

• There is always a change in the protein when a mutation occurs

• Only the mRNA is used in protein synthesis so a mutation in the DNA would have no effect on the protein

Use your codon chart to find the amino acid that codes for AGU

• Tyr

• Gly

• Arg

• Ser

Use your codon chart to find the amino acid that codes for the mRNA codon GCA

• Thr

• Ala

• Pro

• Ser

Amino Acids form a __________ ____ that is then folded into a protein

• Polypeptide Chain

• Protein Chain

• Carbohydrate

• Deoxyribose Nucleic Acid

Any change in the sequence of DNA is...

• transgenic shift
• Single Genotype
• Monohybrid Trait
• Mutation

Why are insertion and deletion mutations so harmful?

• They change all of the codons from the mutation on down the line, which changes the amino acid sequence
• They insert things that an organism doesn't need.
• They often delete things that organisms need.
• Insertion and deletions are not any more harmful than substitution mutations.
