1. DNA (which stands for Nobel Prizeamino acidscell lifedeoxyribonucleic aciddiseasesdouble helixgenetic codegenomehaemoglobinmoleculesmutationnucleotidesorganismresearcherstissues I don't know) is one of the most important elements in living cells.

2. DNA can be compared to the programming code in a computer. Indeed, DNA contains all the information necessary for
Nobel Prizeamino acidscell lifedeoxyribonucleic aciddiseasesdouble helixgenetic codegenomehaemoglobinmoleculesmutationnucleotidesorganismresearcherstissues I don't know.

3. DNA is composed of two large Nobel Prizeamino acidscell lifedeoxyribonucleic aciddiseasesdouble helixgenetic codegenomehaemoglobinmoleculesmutationnucleotidesorganismresearcherstissues I don't know which interact with each other.

4. The DNA shape is special and looks like a Nobel Prizeamino acidscell lifedeoxyribonucleic aciddiseasesdouble helixgenetic codegenomehaemoglobinmoleculesmutationnucleotidesorganismresearcherstissues I don't know.

5. That special structure was identified by two English-speaking Nobel Prizeamino acidscell lifedeoxyribonucleic aciddiseasesdouble helixgenetic codegenomehaemoglobinmoleculesmutationnucleotidesorganismresearcherstissues I don't know in 1953.

6. They received a Nobel Prizeamino acidscell lifedeoxyribonucleic aciddiseasesdouble helixgenetic codegenomehaemoglobinmoleculesmutationnucleotidesorganismresearcherstissues I don't know for that scientific discovery in 1962.

7. Each strand of the helix is composed of a series of small molecules called
Nobel Prizeamino acidscell lifedeoxyribonucleic aciddiseasesdouble helixgenetic codegenomehaemoglobinmoleculesmutationnucleotidesorganismresearcherstissues I don't know which are linked to one another. There are four different nucleotides: adenine, guanine, cytosine and thymine.

8. The sequence of nucleotides is very important and defines the Nobel Prizeamino acidscell lifedeoxyribonucleic aciddiseasesdouble helixgenetic codegenomehaemoglobinmoleculesmutationnucleotidesorganismresearcherstissues I don't know.

9. Each living Nobel Prizeamino acidscell lifedeoxyribonucleic aciddiseasesdouble helixgenetic codegenomehaemoglobinmoleculesmutationnucleotidesorganismresearcherstissues I don't know has its own genome which encodes different proteins.

10. The Nobel Prizeamino acidscell lifedeoxyribonucleic aciddiseasesdouble helixgenetic codegenomehaemoglobinmoleculesmutationnucleotidesorganismresearcherstissues I don't know is used to translate the DNA sequence into a protein sequence.

11. Proteins are composed of small blocks called
Nobel Prizeamino acidscell lifedeoxyribonucleic aciddiseasesdouble helixgenetic codegenomehaemoglobinmoleculesmutationnucleotidesorganismresearcherstissues I don't know. The length of the proteins varies from 50 to 25000 amino acids.

12. Proteins are used by organisms to structure cells, to form different cellular
Nobel Prizeamino acidscell lifedeoxyribonucleic aciddiseasesdouble helixgenetic codegenomehaemoglobinmoleculesmutationnucleotidesorganismresearcherstissues I don't know such as liver, lung or brain. But proteins also play a crucial role in regulating cell functions.

13. Each cell is regulated differently, so Nobel Prizeamino acidscell lifedeoxyribonucleic aciddiseasesdouble helixgenetic codegenomehaemoglobinmoleculesmutationnucleotidesorganismresearcherstissues I don't know is more expressed in blood cells than in neuron for example.

14. A single Nobel Prizeamino acidscell lifedeoxyribonucleic aciddiseasesdouble helixgenetic codegenomehaemoglobinmoleculesmutationnucleotidesorganismresearcherstissues I don't know in the DNA induces a modification of the protein.

15. That modification can be responsible for
Nobel Prizeamino acidscell lifedeoxyribonucleic aciddiseasesdouble helixgenetic codegenomehaemoglobinmoleculesmutationnucleotidesorganismresearcherstissues I don't know. The appearance of those diseases can be prevented by adopting a healthy lifestyle.
