Understanding Codon Charts

What is the primary purpose of a codon chart?

• To identify amino acids from mRNA codons

• To find the start codon in DNA

• To decode DNA sequences

• To translate proteins into RNA

When using the first type of codon chart, where do you start reading the codon?

• From the top row

• From the bottom row

• From the right column

• From the left column

What amino acid does the codon CAG code for using the first type of codon chart?

• Stop codon

• Phenylalanine

• Glutamine

• Methionine

How does the codon wheel differ from the first type of codon chart?

• It only identifies stop codons

• It starts from the middle and moves outward

• It uses DNA instead of mRNA

• It starts from the outer circle and moves inward

What does the codon UAG signify when using the codon wheel?

• Start of a protein chain

• A stop codon

• A mutation

• An error in translation
