Amino acids are either synthesised or eaten in food. Then, after the transcription of polypeptide genes, the amino acids are put together. This is done by translation and RNA splicing which produces messenger RNAs. The splicing process produces the final proteins, which then fold up into their protein structure. Then they can function. The plural is used here because, with most genes, the splicing process produces more than one final working protein. One particular Drosophila gene (DSCAM) can be alternatively spliced into 38,000 different mRNA.
