Anotace knihy

For most of human history the rules of inheritance were guessed at. We have had the actual answer for about seventy years, and the ability to edit it for about twelve.

Before anyone knew what a gene was, the best available theory said that children were a blend of their parents, like mixing paint. It had an obvious fatal flaw that nobody could get past: blend anything long enough and all variation disappears. Evolution needs variation. Something was badly wrong.

The answer came from a monastery garden, was ignored for thirty-five years, then rediscovered, argued over, and eventually traced all the way down to a molecule that spells everything out in four letters.

Thirty-eight chapters. No biology background required. The whole arc, from pea plants to a therapy you can now be prescribed.

• Why the blending theory had to be wrong, and what replaced it


• The results so clean that statisticians still argue about them


• What a chromosome actually is, and how the fly room proved genes sit on them


• The experiment that showed heredity is carried by a molecule nobody rated


• The photograph that gave away the structure


• How four letters encode twenty amino acids, and how that was worked out


• What a mutation is, why most of them do nothing, and what the proofreaders catch


• Why the human genome has far fewer genes than anyone predicted


• How a cell remembers what kind of cell it is


• What a polygenic score is really telling you, in plain arithmetic


• The bacterial immune system that turned into programmable scissors


• What happens after the cut, and why that step decides everything


• Editing single letters and writing new sequence without cutting at all


• The hardest unsolved problem in the field, which is simply getting the tool inside


• An approved cure for sickle cell, and what it costs

Including the parts the press coverage skips. What off-target editing means and how it is measured. Why a heritability estimate carries no information whatsoever about whether a trait can be changed, demonstrated with a condition that is almost entirely genetic and almost entirely preventable with different milk powder. And why editing embryos is a different question from editing patients, legally and biologically.

This is the story of how a rule about pea plants became a tool that rewrites living cells, written for people who want to understand the science well enough to judge the headlines.
