Why would this be of any interest to OOL researchers? Do you know what
the eukaryotic 5 prime cap is for mRNA? It is a post transcriptional
modification of the mRNA. Mature mRNA that can be recognized by the
ribosomes and translated into protein have a 5'cap. Light is not needed
for this process.
What these chemical engineers did was to add a modified 5'cap to to
mRNA. The modification is photosensitive so that when light hits the
molecule the addition to the 5'cap is released. The modified 5'cap is
not recognized by the ribosome, but once it releases the modification it
can be recognized.
There isn't anything that relates to the origin of life in this process.
