1. A transcriptome is a collection of messenger RNA molecules derived from genes whose protein products are needed by the cell. It is generated by transcription of mRNA by DNA dependent RNA polymerase and will vary from cell type to cell type and potentially over the lifetime of the cell or in different environments that the cell encounters. ::) 8)

2. A proteome is a cell’s repertoire of proteins; it dictates the cell’s function. It is generated by translation, the process of converting the information in RNA molecules into proteins. 8)
