"Keep your heart with all diligence, For out of it spring the issues of life”
Proverbs 4:23
mRNA
Colin, having copied the recipe by hand at the library, has now arrived back at home. He’s in the kitchen and he has all the necessary ingredients to hand. The next stage is to (1) READ the instructions (2) Put the ingredients into the mixing bowl in the CORRECT ORDER.
The parallel
The ‘photocopy’ of the protein recipe from the DNA template strand, has left the nucleus (the library) and in now in the cytoplasm (the kitchen). All the ingredients (amino acids) are at hand and now the ‘photocopy’ will be READ and the amino acids shall be put in ‘the mixing bowl’ in the CORRECT ORDER.
Cytoplasm
Once the mRNA is out in the cytoplasm it is greeted by a RIBOSOME
RIBOSOME
mRNA
Production site
Acceptor site
The RIBOSOME is made of two subunits
The large subunit is made up of approx
The small subunit is made up of approx
50 proteins
30 proteins
By Design -
‘A typical bacterium has 20,000 ribosomes in each cell’
-
The Ribosome will carry out 4 functions
It will TRANSLATE the code on the mRNA
It will ASSEMBLE the amino acids into a protein
It will READ the code on the mRNA
It will SIGNAL for the amino acids to be brought
