In Star Trek, a molecular reversion field is a spatial anomaly that can interfere with transporter patterns and the molecular structures of objects passing through it. In the Star Trek: The Next Generation episode "Rascals", the shuttlecraft Fermi was trapped in such a field. Traveling aboard the shuttle were Captain Jean-Luc Picard, Ensign Ro Laren, Keiko O'Brien, and Guinan. When the USS Enterprise-D attempted to beam them off the shuttle, the molecular reversion field obscured portions of their patterns, in particular the ribo-viroxic-nucleic structure of their DNA. The transporter re-materialized all four without their ribo-viroxic-nucleic structure, resulting in them being turned into young children, though all their memories and mental capacities remained those of adults.

There certainly does not exist within real science either the terms 'molecular reversion field' or 'ribo-viroxic-nucleic'. The latter does allude to ribonucleic acid (RNA) - a type of molecule that consists of a long chain of nucleotide units - that is very similar to DNA, but differs in a few important structural details: in the cell, RNA is usually single-stranded, while DNA is usually double-stranded; RNA nucleotides contain ribose while DNA contains deoxyribose (a type of ribose that lacks one oxygen atom); and RNA has the base uracil rather than thymine that is present in DNA. RNA is central to the synthesis of proteins and play crucial roles in protein synthesis and other cell activities. Messenger RNA (mRNA) carries the "message" of the DNA to the cytoplasm of cells where protein is made in amino acid sequences specified by the mRNA. Transfer RNA (tRNA) is a short-chain type of RNA present in cells. There are 20 varieties of  tRNA. Each variety combines with a specific amino acid and carries it along (transfers it) leading to the formation of protein with a specific amino acid arrangement dictated by DNA. Ribosomal RNA functions as a nonspecific site for making polypeptides.
