Codon Chart 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 amino acids are encoded by a single codon?

Back

One amino acid is encoded by a single codon.

Front

What is the start codon and its significance?

Back

The start codon is AUG, which codes for Methionine and signals the beginning of protein synthesis.

Front

What is a stop codon?

Back

A stop codon is a codon that signals the termination of protein synthesis. Examples include UAA, UAG, and UGA.

Front

How do you read a codon chart?

Back

A codon chart is read by matching the first two letters of the codon with the corresponding row and column to find the amino acid.

Front

What is the amino acid sequence for the mRNA strand UGU-UGG-AUA-CCC?

Back

Cys-Trp-Ile-Pro.

Front

What is the amino acid sequence for the mRNA strand UGG-ACU-CGA-GUG?

Back

Trp-Thr-Arg-Val.

Front

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

Back

Arg-Phe-Leu-Ala.

Front

What is the amino acid sequence for the mRNA strand AUG-GAC-ACU-UAG?

Back

Met-Asp-Thr-STP.

Front

What is the amino acid sequence for the mRNA strand AAU-UCG-CAA-GGG?

Back

Asn-Ser-Gln-Gly.
