The genetic code links groups of nucleotides in an mRNA to amino acids in a protein. Start codons, stop codons, reading frame.

There are 61 codons for amino acids, and each of them is "read" to specify a certain amino acid out of the 20 commonly found in proteins. One codon, AUG, specifies the amino acid …

As we saw above, the genetic code is based on triplets of nucleotides called codons, which specify individual amino acids in a polypeptide (or "stop" signals at its end).

In an mRNA, the instructions for building a polypeptide come in groups of three nucleotides called codons. Here are some key features of codons to keep in mind as we move forward:

This article covers the foundational concepts of codons, anticodons, the wobble hypothesis, and the universal nature of the genetic code, with applications that are essential for MCAT …

The anticodon of a given tRNA can bind to one or a few specific mRNA codons. The tRNA molecule also carries an amino acid: specifically, the one encoded by the codons that the …

Learn about RNA and protein synthesis in molecular genetics with this high school biology resource from Khan Academy.

These sequences are like a code, where groups of three bases (called codons) specify particular amino acids to build proteins. For example: A segment of DNA with the base sequence ATG …

Frameshift Mutation: If the number of inserted or deleted nucleotides is not a multiple of three, it causes a shift in the reading frame, altering all downstream codons. This can result in a …

Translation occurs in ribosomes, which are cellular structures made of proteins and ribosomal RNA (rRNA). Here, mRNA is converted into amino acid sequences, forming polypeptides. …
