Codon Chart

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 does the codon UUA represent?

Back

Leucine.

Front

What amino acid is represented by the codon ACC?

Back

Threonine.

Front

What is the role of mRNA in protein synthesis?

Back

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

Front

What is transcription in the context of protein synthesis?

Back

Transcription is the process of copying a segment of DNA into mRNA.

If the DNA sequence is GAC CAA TAT GTA, what is the corresponding mRNA sequence?

Back

CUG GUU AUA CAU.

Front

What amino acid does the codon AGG code for?

Back

Arginine.

Front

What is the significance of the start codon AUG?

Back

AUG is the start codon that signals the beginning of protein synthesis and codes for 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
