Centuries later, crawfish season in Louisiana is still exciting, with crawfish boils and backyard parties a time-honored tradition. Commercial sales of crawfish in Louisiana began in the late 1800s.
Deoxyribonucleic acid (/diËÉksiËraÉªbÉµ.njuËËkleÉª.É¨k ËaesÉªd/ ; ËÃ¦SÉªD) dna is a molecule that carries most of the genetic instructions used in the, development functioning and reproduction of all known living organisms and many. viruseshe two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase âeither cytosine (C), guanine (G), adenine (A), or thymine (T)âas well as a monosaccharide sugar called deoxyribose and a phosphate group.
DNA stands for Deoxyribonucleic acid, and it is found in the nucleus of every cell in the human body. DNA is the master plan-it contains all the genetic information needed for a living thing to develop and function.
