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

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.

Front

What is the function of tRNA?

Back

tRNA (transfer RNA) is responsible for bringing amino acids to the ribosome during protein synthesis, matching them to the codons on the mRNA.

Front

What does the term 'amino acid sequence' refer to?

Back

The amino acid sequence is the order in which amino acids are linked together to form a protein, determined by the sequence of codons in mRNA.

Front

What is a stop codon?

Back

A stop codon is a codon that signals the termination of protein synthesis, indicating that the polypeptide chain is complete.

Front

What amino acid is represented by the codon AUG?

Back

AUG codes for Methionine, which is also the start codon for protein synthesis.

Front

How many amino acids are there in the genetic code?

Back

There are 20 standard amino acids that are encoded by the genetic code.

Front

What is the significance of the codon chart?

Back

The codon chart is a reference tool that shows the relationship between mRNA codons and the corresponding amino acids they code for.

Front

What is the amino acid sequence for the mRNA strand CCA-GAG-UUU-UAG?

Back

Pro-Glu-Phe-Stop.

Front

Which codon corresponds to the amino acid Glutamine?

Back

The codon CAA corresponds to the amino acid Glutamine.
