GCSE level School Biology Notes: How proteins are synthesised - role of DNA and RNA

SITEMAP   Use page sub-index, follow links on Protein Synthesis

The functions of DNA and RNA in Protein Synthesis and the varied functions of proteins

Doc Brown's biology exam revision study notes:  These pages will help you answer questions such as ...  What is a nucleotide? What is its structure?   What is the structure of DNA? Why is it classed as a polymer?   How does DNA code for amino acids and hence proteins?   What is the function of DNA? How are proteins synthesised?   What is RNA? What is the function of RNA? What is a triplet code? How can we extract DNA from cells?  How do cells make proteins in the cytoplasm? What functions to proteins have in living organisms?
