Web12 feb. 2024 · Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell ‘s activities, while RNA converts that code into proteins to carry out cellular functions. Is RNA important for protein formation? WebThe mystery of the human genome's dark matter: Twenty years ago, an enormous scientific effort revealed that the human genome contains 20,000 protein-coding genes, but they account for just 2% of our DNA. The rest of was written off as junk – but we are now realising it has a crucial role to play. graphic artifacting
