Protein synthesis steps are twofold. Firstly, the code for a protein (a chain of amino acids in a specific order) must be copied from the genetic information contained within a cell… See more

The result of protein synthesis is a chain of amino acids that have been attached, link by link, in a specific order. This chain is called a polymer or polypeptide and is constructe… See more

In the nucleus, two strands of DNA are held together by nitrogenous bases (also called nucleobases or bases). Four bases – cytosine, guanine, adenine, and thymine – form the let… See more

To make the copied stretch of code (transcription) we need enzymes called RNA polymerases. These enzymes gather free-floating messenger RNA (mRNA) molecules i… See more
