Good Protein Synthesis
(To the tune of "Good King Wenceslaus")
Copyright © 2011 Kevin Ahern

David Simmons' recording HERE

Amino acids cannot join

By themselves together

They require ribosomes

To create the tether

 

All the protein chains get made

ÔCording to instruction

Carried by m-R-N-A

In peptide bond construction

 

Small subunit starts it all

With initiation

Pairing up two RNAs

At the docking station

 

Shine DalgarnoŐs complement

In the 16 esses

Lines the A-U-G up so

Synthesis commences

 

Elongation happens in

Ribosomic insides

Where rRNA creates

Bonds for polypeptides

 

These depart the ribosome

Passing right straight through it

In the tiny channels there

Of the large subunit

 

Finally when the sequence of

One of the stop codons

Parks itself in the A site

Synthesis canŐt go on

 

P-site RNA lets go

Of what it was holding

So the polypeptide can

Get on with its folding
