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

How are the instructions for building a protein encoded in DNA, and how are they deciphered by the cell? In this article, we'll take a closer look at the genetic code, which allows DNA and RNA …

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

The genetic code is read in three-base words called codons. Each codon corresponds to a single amino acid (or signals the starting and stopping points of a sequence).

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 …

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 goal itself of the two processes is different. DNA replication aim to produce a copy of the genetic information and RNA trancription aim to ultimately (in most cases) produce a protein.

Learn about how the information in an mRNA sequence is decoded to make a polypeptide.

These shared features suggest that all living things are descended from a common ancestor, and that this ancestor had DNA as its genetic material, used the genetic code, and expressed its …
