Mutations and DNA

The bottom DNA sequence in the image has been altered by this type of mutation

• substitution

• insertion

• deletion

• translocation

NGSS.HS-LS3-2

A segment of DNA has base sequence GAC GAC CGC AAA ACA AGC. Due to deletion, the first base G is deleted. The likely effect of this on the coding of DNA segment is that

• the first amino acid will be different and all other will be like the original polypeptide.

• there will be no change in the polypeptide chain.

• the whole sequence of amino acids will be changed.

• the polypeptide chain will be two amino acids shorter

• substitution

• insertion

• deletion

Why are insertion and deletion mutations so harmful?

• They change all of the codons following the mutation, 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.

What would happen to this DNA sequence if a deletion mutation occurred?

• The mutation would cause the mRNA to STOP early.

• The mutation would cause the sequence to be shifted to the left, changing amino acids in the protein.

• The mutation is a point mutation and will be silent because the amino acid did not change.

• The mutation is a frameshift mutation but will not change any amino acids.
