The novel microRNAs, target sites, and sense-antisense transcript arrangement that we discovered are conserved among monocots, indicating that this pathway is at least 50 million years old, Meyers noted. The next ...

If the same molecule of DNA is transcribed into antisense RNA, then the transcript has the reverse sequence as the original DNA sequence. Antisense RNA transcripts can exert function because they can bind to the RNA transcripts fo...
