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.
Transcript: The structure of DNA, that Watson and Crick discovered, suggests how genetic information is passed on. Before a cell divides, the double helix unwinds and the two strands of the DNA molecule in the nucleus separate.Each strand is then used as a template for the construction of new DNA molecules. The replication of DNA is simple in theory, but much more complicated in reality.ranscript: The structure of DNA, that Watson and Crick discovered, suggests how genetic information is passed on.
