Document Summary
Gene expression process where dna directs the synthesis of proteins, or in some cases just rnas. Expression of genes that that code proteins includes two stages: transcription, translation. Genes provide the instructions for making specific proteins: does not build the protein directly. Dna leads to nucleic acid rna leads to protein synthesis: rna is similar to dna except that rna contains: ribose not deoxyribose, nitrogenous base of uracil not thymine, dna: a, g, c, t. Rna: a, g, c, u: rna is a single strand. Monomers are the four types of nucleotides which differ in nitrogenous bases, convey information. Genes are typically hundreds or thousands of nucleotides long, each having a specific sequence of nucleotides. Each polypeptide of a protein also has monomers arranged in a particular linear order (protein primary structure) but its monomers are amino acids. Transcription is the general term for the synthesis of any kind of rna on a dna template.
