Abstract

As a first approximation, genes can be defined as stretches of DNA that encode a single protein or a single functional RNA, such as an rRNA or tRNA. There are exceptions to this rule because there are mechanisms, such as alternative splicing of the primary RNA transcript into different mRNAs, that may intervene between a given gene and a finished protein. As a result, in some cases a single gene may actually encode multiple proteins.
