• Make protein

• Make cells

• Make DNA

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

Why must transcription occur in the nucleus?

• because DNA can't leave the nucleus

• because ribosomes are in the nucleus

• because DNA polymerase is found there

• because helicase unzips the DNA

How many nucleotides code for 1 amino acid?

• 1

• 2

• 3

• 4

Which process does this diagram illustrate?

• transcription

• DNA replication

• translation

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

Original DNA = TAC GAC TTG AAT

Mutated DNA = TAC GTA CTT GAA T

What type of mutation has occurred?

• Chromosomal mutation

• Point mutation

Match the following

• a type of mutation where large sections of the chromosome are affected

• Chromosomal mutation

• a type of mutation caused by adding or deleting bases, affecting all the codons after the change

• Point mutation

• a change in the DNA sequence

• Frameshift mutation

• a type of mutation where one to few bases are substituted with different bases

• Mutation

• a type of mutation that doesn't result in a change in the amino acid sequence (same protein)

• Silent mutation
