WebGene Signatures are sets of genes to report a consensus signal or function. They are not defined in a particular way but can be defined by any chosen group depending on the biological function that you are interested in. Typically these are defined by differential gene expression analysis or principal component analysis, although other approaches such as … Web1. DNA does not contain introns. 2. Some genes are organized into operons and mRNA transcripts often specify more than one protein. 3. mRNA can be transcribed from DNA and translated into protein at the same time.
