Activated charcoal works by adsorption, which is an electrical action, rather than absorption, which is a mechanical action. Activated charcoal adsorbs most organic and inorganic chemicals that do not belong in the body, but no studies have been able to prove that it adsorbs nutrients, as some people are afraid of.
A molecule of DNA is double-stranded. The molecule has the shape of a double helix, typically right handed (B form DNA). The DNA molecule consists of two complementary strands oriented in an antiparallel fashion. Each strand is composed of nucleotides.
DNA Structure. DNA structure An overview. The DNA structure consists of two chainlike molecules (polynucleotides) that twist around each other to form the classic double-helix. The cell s machinery forms polynucleotide chains by linking together four nucleotides.
