What is the simple definition of DNA

16 what happens if acid is dissolved in water explain with an example?Dna, short for deoxyribonucleic acid, is the molecule that contains the genetic code of organisms.It is a chemical made up of two long molecules, arranged in a spiral.Dna is made up of molecules called nucleotides.Dna's unique structure enables the molecule to copy itself during cell division.

Dna is considered a genetic blueprint for an organism because every cell in the body that contains dna has these instructions, which enable the organism to grow, repair itself, and reproduce.The sides of the ladder are made up of sugars and phosphates, and the rungs are formed by bonded pairs of nitrogenous bases.15 does acid dissolve dna?The structure of dna can be understood in three stages:Dna is the material that carries all the information about how a living thing will look and function.

[1] dna) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses.This video designed for kids is a fun/exciting way to introduce dna to children.A dna molecule is composed of two chains of nucleotides that wind about each other to resemble a twisted ladder.22 how does an acid work?Any of various nucleic acids that are usually the molecular basis of heredity, are constructed of a double helix held together by hydrogen bonds between purine and pyrimidine bases (see base entry 1 sense 6b) which project inward from two chains containing alternate links of deoxyribose and phosphate, and that in eukaryotes are localized chiefly in cell nuclei — compare recombinant dna.

There are around 2.5 billion cells in one of your hands, but they are tiny.Nearly every cell in a person's body has the same dna.These sections are called genes.These bases are adenine (a), guanine (g), cytosine (c), and thymine (t).
