| RNA Explained |
 |
Ribonucleic acid (RNA) is a nucleic acid that
consists of a long chain of nucleotide units.
Each nucleotide consists of a nitrogenous
base, a ribose sugar, and a phosphate. RNA is
very similar to DNA, but differs in a few
important structural details: in the cell,
RNA is usually single-stranded, while DNA is
usually double-stranded; RNA nucleotides
contain ribose while DNA contains deoxyribose
(a type of ribose that lacks one oxygen
atom); and RNA has the base uracil rather
than thymine that is present in DNA.
RNA is transcribed from DNA by enzymes called
RNA polymerases and is generally further
processed by other enzymes. RNA is central to
the synthesis of proteins. Here, a type of
RNA called messenger RNA carries information
from DNA to structures called ribosomes.
These ribosomes are made from proteins and
ribosomal RNAs, which come together to form a
molecular machine that can read messenger
RNAs and translate the information they carry
into proteins. There are RNAs with other
roles, in particular regulating which genes
are expressed, but also as the genome of most
viruses.
