In contrast, trans-regulatory elements are species which may modify the expression of genes distant from the gene that was originally transcribed to create them. To demonstrate the concept (this is not a specific example), a transcription factor which regulates a gene on chromosome 6 might itself have been transcribed from a gene on chromosome 11. This term is constructed from the Latin root -trans, which means "across from".
To summarize, cis- elements are present on the same strand as the gene they regulate whereas trans- elements can regulate genes distant from the gene from which they were transcribed.
