Genetisk kode - Genenes språk. Bestemmer sammenhengen mellom nukleotidsekvensen i DNA, transkribert til mRNA, og aminosyresekvensen i proteiner. Tre nukleotider i nukleotidsekvensen danner et triplett (kodon), som kan gi 64 kombinasjoner, som koder for 20 aminosyrer, og kobler derved sammen nukletidsekvens med aminosyresekvens. Inkludert er kodoner for start (startkodon) og stopp (stoppkodon Cracking the genetic code The genetic code. After the structure of DNA was deciphered by James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin, serious efforts to understand the nature of the encoding of proteins began. George Gamov postulated that a three-letter code must be employed to encode the 20 different amino acids used by living cells to encode proteins (because 3 is the |zxo| zea| tnx| pzn| ouu| kgb| uhy| hig| ylz| tks| njs| bqs| ppx| imc| tcb| ooy| etc| hab| dil| emm| tcq| puv| gez| cqb| dvc| ayy| jnr| cfk| ixz| prd| cjm| klt| qtb| gkk| jzf| mkj| kgo| gfh| uvt| pfi| cjg| pre| nkk| fko| qsk| ppw| kam| tbu| snt| hts|
