Morphology
The phrase is a regular adjective + noun composition: 'informational' (providing information) modifies 'RNA' (a nucleic acid that carries genetic information), so the meaning 'RNA that carries information' is directly derivable from the parts. Although the term is scientific, the compositional pattern is transparent and cross-linguistically predictable, so a learner who knows both words would understand the intended sense.
Etymology
Informational RNA is like a tiny mail carrier inside a cell: informational means it carries 'information' and RNA is the part that carries the message. It brings instructions from DNA in the nucleus to the ribosome, the cell's protein factory, so the cell can build proteins, which is why scientists call it 'messenger RNA' or 'mRNA'.
