Transcription and Translation

This is a codon chart.

A strand of DNA with the sequence GAA CCG GGG undergoes a mutation, and the first G is changed to an A. How will this mutation affect the amino acid sequence?

• All of the amino acids will change.

• All of the amino acids will remain the same.

• One amino acid will change.

• Two amino acids will change.

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

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

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

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

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

Which best describes a strand of DNA?

• It is a double-stranded nucleic acid with deoxyribose and uracil.

• It is a single-stranded nucleic acid with deoxyribose and thymine.

• It is a double-stranded nucleic acid with deoxyribose and thymine.

• It is a single-stranded nucleic acid with ribose and uracil.

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

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

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

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

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

Why is DNA replication considered a semi-conservative process?

• DNA has two sides of complementary base pairs held together by weak bonds.

• RNA will combine with DNA using the base pair rules during this process.

• The new DNA molecules contain one strand of the original molecule and one new strand.

• DNA replication must occur before mitosis to produce identical daughter cells.
