25. Codon Chart - Practice

Front

What is a codon?

Back

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

Front

How many nucleotides are in the codon sequence AAU GCG AUG?

Back

9

Front

What amino acid does the codon CCU code for?

Back

Proline

Front

What is the codon for lysine?

Back

AAG

Front

What amino acid is represented by the codon AUU?

Back

Isoleucine

Front

What is the role of a codon in protein synthesis?

Back

Codons are used to translate the genetic code into amino acids, which are the building blocks of proteins.

Front

How many different codons are there in the genetic code?

Back

There are 64 different codons.

Front

What does the start 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 a stop codon?

Back

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

Front

What is the significance of the genetic code being degenerate?

Back

The genetic code is degenerate because multiple codons can code for the same amino acid, providing redundancy in the genetic code.
