Fig. 2From: Long interspersed nuclear element-1 hypomethylation in cancer: biology and clinical applicationsLINE-1 can produce two types of unique RNA sequences. One type of unique sequence is the result of LINE-1 RNA transcription proceeding beyond the LINE-1 sequence. The other type occurs when the reverse LINE-1 promoter transcribes unique DNA sequences located beyond the 5′ end of LINE-1Back to article page
