Codon Translation and Amino Acids

Mr. Haney explains how to use a codon chart to translate an mRNA strand into amino acids. He demonstrates the process by dividing the mRNA into codons, using the chart to find corresponding amino acids, and emphasizing the importance of the third base in codon variability. The video covers translating four specific codons: CUG, ACC, UAC, and AUU, resulting in the amino acids Leucine, Threonine, Tyrosine, and Isoleucine, respectively.

What is the primary purpose of defining a reading frame when translating mRNA?

• To increase translation speed

• To ensure codons overlap

• To change nucleotide sequences

• To prevent reading errors

How many nucleotides make up a codon?

• Four

• Three

• Two

• Five

Which amino acid does the codon 'CUG' translate to?

• Valine

• Leucine

• Serine

• Glycine

In the codon 'ACC', what role does the third base 'C' play?

• It changes the reading frame

• It stops the translation

• It is ignored

• It determines the amino acid

What amino acid is coded by the codon 'ACC'?

• Histidine

• Proline

• Alanine

• Threonine

Why is the third base important in the codon 'UAC'?

• It is not important

• It determines the amino acid when multiple options exist

• It is used for error correction

• It changes the codon length

Which amino acid does the codon 'UAC' translate to?

• Tyrosine

• Methionine

• Phenylalanine

• Cysteine

What is the final amino acid translated from the codon 'AAU'?

• Glutamine

• Lysine

• Asparagine

• Isoleucine

What is the significance of the third base in codon translation?

• It is always the same

• It can change the amino acid outcome

• It is not used in translation

• It determines the start of translation

What is the overall process described in the video?

• Cell division

• mRNA translation using a codon chart

• Protein synthesis

• DNA replication
