RNA

Biochem ribonucleic acid; any of a group of nucleic acids, present in all living cells, that play an essential role in the synthesis of proteins. On hydrolysis they yield the pentose sugar ribose, the purine bases adenine and guanine, the pyrimidine bases cytosine and uracil, and phosphoric acid

The molecules that actually do the translation are transfer RNA (t-RNA) molecules.
Three families of RNA molecules play prominent roles in gene expression (as described below)--messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).
Meanwhile, other experiments distinguished mRNA from two additional types: transfer RNA, which carries amino acids to the site of protein synthesis; and ribosomal RNA, which occurs in the "workbenches" (ribosomes) on which proteins are made.
The gene for the leusine transfer RNA (trnL) from the chloroplast genome (cpDNA) was amplified using polymerase chain reaction (PCR).
Transfer RNA is one of the biochemical features held in common by all modern life forms, and it has been persuasively argued that tRNA is a remnant of the RNA world.
Translation also requires two other types of RNA: ribosomal RNA (rRNA) of the rough endoplasmic reticulum (present in the cytoplasm) and transfer RNA (tRNA).
In two small samples, the frequency of the common allele of this DNA marker, which was shown to be in the threonine transfer RNA gene in mitochondrial DNA, was significantly greater in a high-IQ group than in a low-IQ group.
With the transition of genetic information from DNA to messenger RNA to transfer RNA to protein now well established (see 1956), the most important unanswered question was which trinucleotide corresponded to which aminoacid.
