Mutations

What is most likely to result when a mutation affects a DNA sequence?

• The codons will be unable to create bonds with the enzymes.

• The nucleic acids will be unable to create bonds with the ribosomes.

• The amino acids sequence will be changed and a different protein will be formed.

• The protein sequence will be changed and a different set of nucleic acids will be formed.

A mutation is which cell can create a change in heritable traits?

• body cell

• gamete cell

• somatic cell

• prokaryotic cell

Which statement best explains how mutations change the shape of flu virus antigens, preventing he attachment of antibodies?

• Mutations allow for the exchange of antigens among virus species.

• Mutations cause overproduction of new antigens on the surface of the virus

• Mutations change the amino acid sequence of the protein, resulting in a change in the nucleotide sequence.

• Mutations change the nucleotide sequence of the gene, resulting in a different arrangement of amino acids.

When is the amino acid sequence of a protein most likely to be altered?

• When the protein experiences a change in function.

• When there is a change in the DNA sequence that codes for the protein.

• When the ribosome changes the order in which the amino acids are placed.

• When the environment of the cell becomes warm enough to denature the protein.
