Codon practice

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or a stop signal during protein synthesis.

Front

How many nucleotides make up a codon?

Back

Three nucleotides.

Front

What is the role of codons in protein synthesis?

Back

Codons specify the sequence of amino acids in a protein during translation.

Front

What does the codon AUG signify?

Back

AUG is the start codon that signals the beginning of protein synthesis and codes for the amino acid Methionine.

Front

What is the significance of stop codons?

Back

Stop codons signal the termination of protein synthesis, indicating that the polypeptide chain is complete.

Front

List the three stop codons.

Back

UAA, UAG, UGA.

Front

What amino acid does the codon UAA code for?

Back

UAA codes for a stop signal.

Front

What is the amino acid sequence for the mRNA codons AGG-UUC-CUG-GCC?

Back

Arginine - Phenylalanine - Leucine - Alanine.

Front

What is the amino acid sequence for the mRNA codons GUA-CAU-UUG-AGA?

Back

Valine - Histidine - Leucine - Arginine.

Front

What amino acid does the codon AUU code for?

Back

AUU codes for Isoleucine.
