We wrote of “the national DNA” in a comment article about Nigel Farage’s return from the wilderness, saying that it includes “the presumption … of denying extremists parliamentary seats”. Julian Self wrote to draw my attention to this flagrant breach of my Banned List, the DNA metaphor being one of its prohibited cliches.

For some trait to be “in someone’s DNA” is bad enough, but in a nation’s DNA is too much.

Sorry to report that the same article also included this description of Farage’s imagined feelings on the night of the 2016 referendum: “No victory in modern politics can have felt more pyrrhic.” What we meant was that it was, for the Ukip leader, a hollow victory, because it appeared to condemn him to obscurity. (Indeed, there were commentators who said before the referendum that in five years’ time we will have forgotten who Nigel Farage was. How wrong I turned out to be.)

Anyway, the original pyrrhic victory, won by Pyrrhus, the Greek general, against the Roman republic in 279BC, was a victory won at too great a cost. “If we are victorious in one more battle with the Romans, we shall be utterly ruined,” Pyrrhus is supposed to have said. That wasn’t how we meant to describe the Leave victory in the referendum – the Leave side seem to have ruined themselves quite efficiently since then, but not because of the 2016 campaign.

Naked spirit: In an interesting article, the author said: “I wouldn’t want to be bearing my soul to someone I picked up in a club.” Nothing wrong with that, really. There is no reason why the common phrase shouldn’t refer to carrying one’s soul about as if for display. But the original metaphor was of unclothing the soul and rendering it bare, hence “baring my soul”.

Weights and measures: “Cassowaries are similar to emus and are among the largest bird species in the world, weighing up to 60kg and reaching up to 6ft in height,” we said in our report of a 75-year-old man killed by the large flightless bird he kept at his home in Florida.

As John Schluter pointed out, we were mixing our metric and imperial measures. I would say in our defence that this reflects common usage – except that the first person in the office I asked said they would give their weight in stones and pounds. So perhaps we should have said nine and a half stone.

The best part of that story, though, was this paragraph: “A woman who identified herself as the victim’s partner told the Gainesville Sun newspaper that he had died ‘doing what he loved’.”

Deoxyribonucleic acid in brief

Deoxyribonucleic acid is a molecule composed of two chains that coil around each other to form a double helix carrying the genetic instructions used in the growth, development, functioning, and reproduction of all known organisms and many viruses. DNA and ribonucleic acid (RNA) are nucleic acids; alongside proteins, lipids and complex carbohydrates (polysaccharides), nucleic acids are one of the four major types of macromolecules that are essential for all known forms of life.

The two DNA strands are also known as polynucleotides as they are composed of simpler monomeric units called nucleotides. Each nucleotide is composed of one of four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A] or thymine [T]), a sugar called deoxyribose, and a phosphate group. The nucleotides are joined to one another in a chain by covalent bonds between the sugar of one nucleotide and the phosphate of the next, resulting in an alternating sugar-phosphate backbone. The nitrogenous bases of the two separate polynucleotide strands are bound together, according to base pairing rules (A with T and C with G), with hydrogen bonds to make double-stranded DNA.

The complementary nitrogenous bases are divided into two groups, pyrimidines and purines. In DNA, the pyrimidines are thymine and cytosine; the purines are adenine and guanine.
