Inhaltsangabe

Walter Isaacson’s #1 New York Times bestselling history of our third scientific revolution: CRISPR, gene editing, and the quest to understand the code of life itself, is now adapted for young readers!

When Jennifer Doudna was a sixth grader in Hilo, Hawaii, she came home from school one afternoon and found a book on her bed. It was The Double Helix, James Watson’s account of how he and Francis Crick had discovered the structure of DNA, the spiral-staircase molecule that carries the genetic instruction code for all forms of life.

This book guided Jennifer Doudna to focus her studies not on DNA, but on what seemed to take a backseat in biochemistry: figuring out the structure of RNA, a closely related molecule that enables the genetic instructions coded in DNA to express themselves. Doudna became an expert in determining the shapes and structures of these RNA molecules—an expertise that led her to develop a revolutionary new technique that could edit human genes.

Today gene-editing technologies such as CRISPR are already being used to eliminate simple genetic defects that cause disorders such as Tay-Sachs and sickle cell anemia. For now, however, Jennifer and her team are being deployed against our most immediate threat—the coronavirus—and you have just been given a front row seat to that race.

Chapter One: Hilo

CHAPTER ONE Hilo

If she had grown up in any other part of America, Jennifer Doudna might have felt like a regular kid. But in Hilo, an old town in a volcano-filled region on Hawaii’s “Big Island,” the fact that she was blond, blue-eyed, and lanky made her feel like a complete freak. Her classmates called her a haole, a negative term for people who weren’t Native Hawaiians. Feeling so different made her become skeptical of others and careful about the situations she chose to get herself into, even though later in life she became very friendly and open to new experiences.1

Her family often told Doudna and her sisters stories about their ancestors. One of the more popular tales involved one of Doudna’s great-grandmothers, who was part of a family of three brothers and three sisters. The parents could not afford for all six children to go to school, so they decided to send the three girls. One daughter became a teacher in Montana and kept a diary that has been handed down over the generations. Its pages were filled with tales of determination, hard work, and long hours in the family store, and other frontier pursuits.

“She was crusty and stubborn and had a pioneering spirit,” said Doudna’s sister Sarah, who now has the diary.

In fact, she was a little like her great-granddaughter Jennifer Doudna.

Doudna was also one of three sisters, although there were no brothers. As the oldest, she was spoiled by her father, Martin Doudna, who sometimes referred to his children as “Jennifer and the girls.” She was born February 19, 1964, in Washington, DC, where her father worked as a speechwriter for the Department of Defense. More than anything else, he wanted to be a professor of American literature, so he moved to Ann Arbor, Michigan, with his wife, a community college teacher named Dorothy, and enrolled at the University of Michigan.

When he earned his PhD, Martin applied for fifty jobs and got only one offer, from the University of Hawaii at Hilo. He borrowed $900 from his wife and moved his family there in August 1971, when Doudna was seven.

That’s when Doudna began to feel alone and isolated, especially at school.

In the third grade, she was so unloved by her classmates that she had trouble eating, and she developed all sorts of digestive problems that she later realized were stress related. Kids teased her every day—especially the boys, because unlike them she had hair on her arms. To protect herself, she escaped into books and developed a defensive layer.

There’s an internal part of me they’ll never touch, she told herself.

Many creative people—including Leonardo da Vinci, Albert Einstein, Oprah Winfrey, and Malala Yousafzai—grew up feeling slightly alienated from their surroundings. Like them, Doudna started to become curious about where humans belong in the universe. Digging deep and reading everything she could get her hands on, Doudna tried to figure out who she was in the world and how we all got here.

Fortunately, this loneliness did not last forever. Life began to get better halfway through third grade, when her family moved from the heart of Hilo to a new development of houses that had been carved into a forested slope on the edge of the Mauna Loa volcano. She switched from a large school, with sixty kids per grade, to a smaller one with only twenty. There they studied US history, a subject that made her feel more connected to her roots and less like an outsider.

“It was a turning point,” she recalled.

Doudna thrived so much that by the time she was in fifth grade, her math and science teacher urged her to skip a grade. Her parents agreed and moved her into sixth grade, and that year she finally made a close friend, a girl with whom she has kept in close contact her whole life. Lisa Hinkley (now Lisa Twigg-Smith) was from a classic mixed-race Hawaiian family: part Scottish, Danish, Chinese, and Polynesian. She knew how to handle the bullies.

“When someone would call me a… haole, I would cringe,” Doudna recalled. “But when a bully called Lisa names, she would turn and look right at him and give it right back to him. I decided I wanted to be that way.”

One day in class the students were asked what they wanted to be when they grew up. Lisa proclaimed that she wanted to be a skydiver. Doudna thought that was so cool. Lisa was bold in a way Doudna had never been. So Doudna told herself she needed to learn to be brave, and soon she started to be. Doudna and Lisa spent their afternoons riding bikes and hiking through sugarcane fields, where the biology was lush and diverse, with moss and mushrooms, peach and arenga palms. They found meadows filled with lava rocks covered in ferns, and in the lava-flow caves there lived a species of spider with no eyes. Doudna wondered, How did this spider come to be? She was also intrigued by a thorny vine called hilahila or “sleeping grass,” because its fernlike leaves curl up when touched.2

We all see the wonders of nature every day, whether it be a plant that moves or a sunset that reaches its pink finger rays into a sky of deep blue. The key to true curiosity is pausing to think about the causes. What makes a sky blue or a sunset pink or a leaf of sleeping grass curl?

Doudna was curious about all those things and more, and she soon found someone who could help answer such questions. Her parents were friends with a biology professor named Don Hemmes, and he and Doudna’s family loved to go on nature walks together. They especially liked hunting for mushrooms, which was Hemmes’s scientific interest. After photographing the fungi, he would pull out his reference books and show Doudna how to identify them. He also collected microscopic shells from the beach, and he would work with her to categorize them so that they could try to figure out how they evolved.

Doudna’s exploration also continued at home. Her father bought her a horse, a chestnut male named Mokihana after a Hawaiian tree with a fragrant fruit. She joined the soccer team, playing halfback, a position that had been hard to fill because it required a runner with long legs and lots of stamina. At school, math was her favorite class because it felt like detective work.

Although she began doing well academically, she did not feel that teachers at her small school on the outskirts of Hilo expected much of her. She had an interesting response to that, though—the lack of challenges made her feel free to take more chances.

“I decided you just have to go for it,” she recalled. “It made me more willing to take on risks, which is something I later did in science when I chose projects to pursue.”

Her father was the one person who really pushed her. He saw his oldest daughter as his soul mate in the family, the intellectual who was bound for college and an academic career like him. Doudna felt like she was the son he’d always wanted to have, and that was why he treated her a bit differently than he treated her sisters.

Doudna’s father was a huge reader who would check out a stack of books from the local library each Saturday and finish them by the following weekend. Often he would bring home a book for Doudna to read. And that is how a paperback copy of James D. Watson’s...
