Essentially, the airplane undergoes an annual inspection in pieces, in 25-, 50-, or 100-hour segments. The idea is that, say, control cables need not be inspected at every stop but should be seen once a year.
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. virusesell division is essential for an organism to grow, but, when a cell divides, it must replicate the DNA in its genome so that the two daughter cells have the same genetic information as their parent. The double-stranded structure of DNA provides a simple mechanism for DNA replication.
structure and function of genes g enetic information is stored in dna and the expression of this information requires several steps that flow in one direction genes are segments of dna encoding information that ultimately direct the production of rna molecules that serve a variety of functions that includetructure of dna the molecular structure of dna forms a double helix with a backbone of each strand of the helix consisting of a repeating sugar phosphate sugar phosphate polymer the sugar is deoxyribose
