Decoding messages is also a key step in gene expression, in which information from a gene is read out to build a protein. In this article, we'll take a closer look at the genetic code, which allows DNA and …

In this article, we'll take a closer look at the genetic code, which allows DNA and RNA nucleotide sequences to be translated into the amino acids they represent.

This exercise tests knowledge on interpreting the genetic code, translation and mutations.

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 preparation.

During translation, the nucleotides of the mRNA are read in groups of three called codons. Each codon specifies a particular amino acid or a stop signal. This set of relationships is known as the genetic code.

Oops. Something went wrong. Please try again. Uh oh, it looks like we ran into an error. You need to refresh. If this problem persists, tell us.

To see how the codon table works, let's walk through an example. Suppose that we are interested in the codon CAG and want to know which amino acid it specifies.

The results of this experiment are presented in Table 1. The table shows the counts per minute per milligram of protein produced when poly-uracil RNA was added ("+") compared to when it was not …

A tRNA with the anticodon CUA will pair with the mRNA codon GAU. According to the genetic code, the mRNA codon GAU specifies the amino acid aspartic acid (Asp).
