The study, which was carried out on just 1% of our DNA code, challenges the view that genes are the main players in driving our biochemistry. Instead, it suggests genes, so called junk DNA and other elements, together weave an intricate control network. ... He explained that the study had found junk DNA was being transcribed, or copied, into RNA - an active molecule that relays information from DNA to the cellular machinery. He added:...

 genome human RNA DNA genetics
US scientists believe they have uncovered one of the mechanisms that enables the brain to form memories. Synapses - where brain cells connect with each other - have long been known to be the key site of information exchange and storage in the brain. But researchers say they have now learnt how molecules at the site of the synapse behave to cement a memory.

 memory Alzheimer's brain synapse RNA genetics
MicroRNAs from common plant crops such as rice and cabbage can be found in the blood and tissues of humans and other plant-eating mammals, according to a study published today in Cell Research. One microRNA in particular, MIR168a, which is highly enriched in rice, was found to inhibit a protein that helps removes low-density lipoprotein (LDL) from the blood, suggesting that microRNAs can influence gene expression across kingdoms.
