1
RNA stands for ribonucleic acid and it is present in several fundamentally important
biochemical situations.
2
Cells have a specific kind of molecular particle, containing protein and RNA chains,
called the ribosome, which does this job.
3
Strictly 2′-deoxynucleotides if you know your ribose sugar chemistry.
4
By special proteins called helicases.
5
The RNAs that don’t act as messengers often have a direct physical role in
biochemistry, just like proteins.
6
This example uses the Protein Data Bank naming system.
7
The versions of a chemical element with different atomic weights, caused by different
numbers of neutrons in the nucleus.
8
A means of separating molecules in a sample according to size, by passing an electric
current through a gelatinous substance in which differently sized chains move at different
speeds.
9
The part that differs between each kind of amino acid.
