Real-time monitoring of RNA splicing in living cells moves step closer with novel fluorescent probe
Numerous biological processes depend on molecules called lariat RNAs (LaRNAs). These lasso-shaped structures form in the cell during RNA splicing. During this process, transcribed RNA strands convert to messenger ...

New details about gene regulation explained
(Phys.org) -- When genetic information is read from the genetic blueprint DNA, RNA polymerase II translates it into RNA molecules. The C-terminal domain, abbreviated as CTD, is an important area of the polymerase ...

Research uncovers new exception to decades-old rule about RNA splicing
There are always exceptions to a rule, even one that has prevailed for more than three decades, as demonstrated by a Cold Spring Harbor Laboratory (CSHL) study on RNA splicing, a cellular editing process. The rule-flaunting ...

Study reveals how ribosomes override their blockades
Ribosomes are "protein factories" in the cells of all living things. They produce proteins based on existing genetic codes stored on special nucleic acid molecules. These molecules, also called messenger RNA (mRNA) due to ...

Molecular alternatives to DNA, RNA offer new insight into life's origins
Living systems owe their existence to a pair of information-carrying molecules: DNA and RNA. These fundamental chemical forms possess two features essential for life: they display heredity—meaning they can encode and ...
