Severo Ochoa discovered RNA
a chemist by the name of Ascoli discovered uracil (a pyrimidine), which is unique to RNA.
Ribonucleic acid (RNA) was discovered by Phoebus Levene in the early 1900s. He identified RNA as a nucleic acid similar to DNA but with different chemical properties.
messenger: carries genetic information from the nucleus to the cytoplasm.transfer: transfers the necessary sequence by carrying the code.ribosomal: helps in synthesis of proteins.
The three main kinds of RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). mRNA carries genetic information from the DNA to the ribosome for protein synthesis, tRNA brings amino acids to the ribosome during translation, and rRNA forms the core structure of the ribosome and catalyzes protein synthesis.
The RNA that is in the shape of a cloverleaf is transfer RNA (tRNA), while the RNA that is in the shape of a hairpin is messenger RNA (mRNA) or microRNA (miRNA). These structures are important for the function and stability of these RNA molecules in cells.

As far as I know: America Wendell Stanley in 1935 crystallized an infectious particle, now known as tobacco mosaic virus (RNA virus)
Thomas Cech and Sidney Altman discovered that RNA can act as its own catalyst, a finding that earned them the Nobel Prize in Chemistry in 1989. Their work demonstrated the catalytic properties of RNA molecules, challenging the traditional belief that only proteins could catalyze biological reactions.
A plant pathologist discovered an infectious RNA particle smaller than a virus that causes diseases in plants. He called it a viroid. Millions each year are lost by these viroids. These contain only RNA.
RNA has been found in a panoply of human body fluids: blood, urine, have since discovered this type of RNA silencing in many orginisms.
The German biochemist Albrecht Kossel discovered the cytosine in 1894. The cytosine is found in DNA and RNA. Its structure was proposed and synthesized in 1903.
Some typewriter manufacturer. kidding aside- I think you mean Transfusion. Blood transfusion became commercially viable around l937. Dr. Charles Drew, a Black physician, was primarily responsible for the advancement. For some odd reason, he was never awarded the Nobel prize.

RNA polymerase is an enzyme that makes a RNA copy from an RNA template.
The three types of RNA are: mRNA (messanger RNA), rRNA (ribosomal RNA), and tRNA (transfer RNA).
mRNA - messenger RNA tRNA - transfer RNA rRNA - ribosomal RNA
