Abundant in the swamps and marshes across south Louisiana, crawfish were a favorite food of early residents. 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.
Genes are the basic functional units of DNA. Your DNA contains instructions to build every single molecule in your body. It is the blueprint for you. On the molecular level, humans are 99.9% exactly the same! The difference between you and someone on the other side of the planet is only .01% of your genes. To get even stranger, the genetic difference between humans and monkeys is only 99.8%! Even strangerâ¦ 97.5% of our DNA is exactly the same as that of a mouse! Thatâs only a 2.5% difference in genetic information.
