These “soluble RNAs” are now called transfer RNAs and mediate the translation of messenger RNAs on ribosomes according to the rules contained in the genetic code. Crick imagined that his adaptors would be small, perhaps 5-10 nucleotides long.
These “soluble RNAs” are now known as transfer RNAs and function as linkers between messenger RNAs and ribosomes, following the rules specified in the genetic code. Crick envisioned his adapters to be compact, roughly 5-10 nucleotides in length.
