Well, while you're correcting the fellow/lass, maybe mention "intron" and "exon"?

Certainly.

The genome is divided into "Introns" and "Exons". Exons are the part of DNA that actually codes for genes, introns sit in the middle not coding. When a gene is expressed the whole sequence is transcribed into RNA. The introns are then 'sliced' from the RNA leaving just the coding section, this RNA (called messenger RNA) binds with other RNA called Ribosomes, these read the mRNA and build proteins.

Example

deaeg3w4yr r3qtibos3t5ome ple32455ase mareht5ke soge46me pr35bot875ein

This is the DNA, it's faithfully transcribed to RNA which then has the introns removed

dear ribosome please make some protein

re: bolding:

Heh... thanks Ryan_m_b, artfully said!

I have a 1934 edition. What to compare figures?

Yeah, compare the masses of the three pions $\pi^{0}$, $\pi^{+}$, and $\pi^{-}$
