Q How are the concepts of the DNA, gene, and proteins characteristics of living beings related?
Characteristics of organisms depend on chemical reactions that take place in them. These reactions are catalyzed by enzymes, extremely specific proteins. Every protein of an organism is made from information contained in RNA molecules that are made according to a template sequence of nucleotides of the DNA chain.
A gene is a DNA polynucleotide sequence that holds information for the production of a proteain.
