The primary nucleobases are cytosine (DNA and RNA), guanine (DNA and RNA), adenine (DNA and RNA), thymine (DNA) and uracil (RNA), abbreviated as C, G, A, T, and U, respectively.

In transcription, the codons of a gene are copied into messenger RNA by RNA polymerase.

RNA provides the information for protein.

An important step was later realization (in 1960) that the messenger RNA was not the same as the ribosomal RNA.

A virus has either a DNA or an RNA genome and is called a DNA virus or an RNA virus, respectively.

RNA viruses Replication usually takes place in the cytoplasm.

And we knew, basically, DNA provides the information for RNA.

For example, we can inhibit genes now with RNA interference.

There are many sentences about DNA, but none about RNA.

Ribosomal RNA (rRNA) is the catalytic component of the ribosomes.

Reverse transcribing viruses with RNA genomes (retroviruses), use a DNA intermediate to replicate, whereas those with DNA genomes (pararetroviruses) use an RNA intermediate during genome replication.

Similar to the 1967 experiments, the infectious RNA was synthesized enzymatically.

Prions are infectious protein molecules that do not contain DNA or RNA.

Many viruses have a replication strategy that involves double stranded RNA (dsRNA).

In the case of genes encoding proteins, that RNA produced from this process is messenger RNA (mRNA), which then needs to be translated by ribosomes to form a protein.

A short time later, this virus was separated into protein and RNA parts.

When such a virus infects a cell, it releases its RNA molecule or molecules, which immediately bind to a protein complex called a dicer that cuts the RNA into smaller pieces.

For about three years we just I tried to solve the structure of RNA.

Of these, only two families have RNA genomes and only five families are enveloped.

Chromatin is a complex of macromolecules found in cells, consisting of DNA, protein and RNA.

RNA viruses can be placed into four different groups depending on their modes of replication.

Ribonucleic acid (RNA) acts as an interpreter in a process called transcription (the reading of genes).

And that let Marshall Nirenberg, you know, take RNA synthetic RNA put it in a system making protein. He made polyphenylalanine, polyphenylalanine. So that's the first cracking of the genetic code, and it was all over by 1966.

In contrast to DNA, which only occurs in the nucleus, RNA is also found in the cytoplasm.

The functional form of single stranded RNA molecules, just like proteins, frequently requires a specific tertiary structure.
