From the Ted Talk by Paul Rothemund: Playing with DNA that self-assembles
Unscramble the Blue Letters
It's what happens in proteins. When this amino-acid sequence gets pucnrenood as atmos, these little letters are sticky for each other. It collapses into a three-dimensional shpae that turns it into a nanomachine that actually cuts DNA. The interesting thing is that if you change the sequence, you change the three-dimensional folding. You get, now, a DNA stapler, instead. These are the kind of molecular programs we want to be able to write. The problem is, we don't know the mhicnae language of proteins or have a compiler for proteins.
Open Cloze
It's what happens in proteins. When this amino-acid sequence gets __________ as _____, these little letters are sticky for each other. It collapses into a three-dimensional _____ that turns it into a nanomachine that actually cuts DNA. The interesting thing is that if you change the sequence, you change the three-dimensional folding. You get, now, a DNA stapler, instead. These are the kind of molecular programs we want to be able to write. The problem is, we don't know the _______ language of proteins or have a compiler for proteins.
Solution
- atoms
- pronounced
- machine
- shape
Original Text
It's what happens in proteins. When this amino-acid sequence gets pronounced as atoms, these little letters are sticky for each other. It collapses into a three-dimensional shape that turns it into a nanomachine that actually cuts DNA. The interesting thing is that if you change the sequence, you change the three-dimensional folding. You get, now, a DNA stapler, instead. These are the kind of molecular programs we want to be able to write. The problem is, we don't know the machine language of proteins or have a compiler for proteins.
