During Larry Nassar's sexual abuse trial and sentencing, victims' harrowing stories have brought to light Ehlers-Danlos Syndrome (EDS), a condition that is common among gymnasts, but poorly understood.
A mechanism by which different forms of mature mRNAs are generated from the same gene. Alternative splicing is a regulatory mechanism by which variations in the incorporation of the exons, or coding regions, into mRNA leads to the production of more than one related protein, or isoform. RNA interference.
This is called the RNA world hypothesis. Why RNA? It can encode genetic instructions (like DNA), and some RNAs can carry out chemical reactions (like proteins). Therefore, it solves the chicken-and-egg problem of which of these two molecules came first. Other evidence also suggests that RNA may be the most ancient of the organic molecules.
