25. 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 stop signal during protein synthesis.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where it is translated into a protein.

Front

What does the codon chart represent?

Back

The codon chart shows the relationship between codons (triplets of nucleotides) and the amino acids they code for.

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 determine the amino acid from a given codon?

Back

To determine the amino acid from a codon, refer to the codon chart that matches the three-nucleotide sequence to its corresponding amino acid.

Front

What is the amino acid sequence for the codon AUG?

Back

The amino acid sequence for the codon AUG is Methionine.

Front

What is the amino acid sequence for the codon UUU?

Back

The amino acid sequence for the codon UUU is Phenylalanine.

Front

What is the amino acid sequence for the codon CCA?

Back

The amino acid sequence for the codon CCA is Proline.

Front

What is the significance of the sequence AUG-CCG-UGA?

Back

This sequence includes a start codon (AUG), a coding codon (CCG for Proline), and a stop codon (UGA), indicating the start and end of protein synthesis.
