2)	enhancers are cis-acting binding sites that bind specific trans-acting transcription factors

3)	enhancers are located immediately upstream of eukaryote promoters

4)	enhancers code for transacting transcription factors to promote gene expression

5)	enhancers bind directly to RNA polymerase II to initiate transcription

Expression of a gene in a mammal can sometimes be associated with the parent from which the gene was inherited (mother or father). What term is used to describe the situation where an allele that is inherited from the mother is expressed, but the homologous allele inherited from the father is not?
