Explore the structure and coding of DNA, the molecule present in every cell nucleus that carries our genetic information. Learn about the composition of DNA, its role in determining amino acid order, and the redundancy of the genetic code.

DNA: Deoxyribonucleic acid Comenius meeting Vienna 2014
DNA: Deoxyribonucleic acid • present in every cell nucleus • identical in each cell of an individual • carrier of the genetic information Fig.: Human cell nucleus, state: interphase u-helmich.de/bio/gen/reihe3/31/index31.html
What is the structure of the DNA? The backbone is composed of: The „rungs“ are the base pairs A T C G Sugar (Deoxyribose) and Phosphate group The order of the bases determines the order of the amino acids. Fig.: webmic.de
