Key Concepts

Codon

A codon is a group of three nucleotides in mRNA that specifies a particular amino acid or a stop signal during protein synthesis. The concept is central to the translation process as each codon correlates with one amino acid according to the genetic code.

Genetic Code

The genetic code is the set of rules that defines how sequences of three nucleotides, or codons, translate into specific amino acids during protein synthesis. It is a nearly universal code used by nearly all organisms, ensuring that the information encoded in the mRNA is accurately converted into the protein's sequence.

mRNA Translation

mRNA translation is the process by which ribosomes interpret the sequence of codons in an mRNA molecule to synthesize a polypeptide chain, which folds into a functional protein. This involves the sequential reading of mRNA, the pairing of codons with tRNA anticodons, and the linkage of the corresponding amino acids.

DNA Transcription and the Coding Strand

During transcription, a segment of DNA is used as a template to synthesize mRNA. The coding strand of DNA, which has the same nucleotide sequence as the mRNA (except that thymine replaces uracil), effectively represents the nucleotide sequence on the chromosome that codes for a protein. This concept links the mRNA sequence back to its original genomic DNA sequence.
