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.
James Watson and Francis Crick proposed a structure for the DNA molecule that suggested the basic mechanism of DNA replication. The model proposes that DNA is composed of two strands of DNA running anti-parallel (remember the 5' and 3' ends!!) to each other.ames Watson and Francis Crick proposed a structure for the DNA molecule that suggested the basic mechanism of DNA replication.
