If a DNA code reads CCAATTGG then the mRNA code would read ____________

• CCAATTGG

•  CCAAUUGG

•  GGUUAACC

•  GGTTAACC

During translation, a ribosome binds to and reads

• DNA

• mRNA

• protein

• a peptide bond

In order for protein synthesis to occur, mRNA must migrate to the

• ribosomes

• lac operon

• RNA polymerase

• heterochromatin

Transcription is the process by which genetic information encoded in DNA is transferred to a(n)

• RNA molecule

• DNA molecule

• uracil molecule

• transposon

Each nucleotide triplet (set of 3 letters) in mRNA that specifies a particular amino acid is called a(n)

• Mutagen

• Codon

• Anticodon

• Exon

An error in DNA replication can cause

• Mutations

• Cancer

• Genetic variation

• All of the above
