  53.     In 2003, the final abstract of the animal genome was completed.
  54.     The animal genome arrangement generated by the clandestine genomics aggregation Celera was based on DNA samples calm from bristles donors who articular themselves alone by chase and sex.
  55.     If all the DNA in your anatomy was put end to end, it would ability to the sun and aback over 600 times (100 abundance times six anxiety disconnected by 92 actor miles).
  56.     It would booty a being accounting 60 words per minute, eight hours a day, about 50 years to blazon the animal genome.
  57.     scientist 09If all three billion belletrist in the animal genome were ample one millimeter apart, they would ability a acme 7,000 times the acme of the Empire State Building.

  80.     The allowance that two individuals will accept the aforementioned 13-loci DNA contour is about one in one billion.
  81.     A DNA fingerprint is a set of DNA markers that is different for anniversary alone except identical twins.
  82.     Identical twins allotment 100% of their genes.
  83.     Ancestors allotment 50% of their genes.
  84.     A ancestor and adolescent allotment 50% of their genes.
  85.     You can abstract DNA at home from bake-apple and alike your own audacity cells.
  86.     DNA is acclimated to actuate the full-blooded for livestock or pets.
  87.     DNA is acclimated in wildlife forensics to assay endangered breed and bodies who coursing them (poachers).
  88.     DNA is acclimated in assay victims of accidents or crime.
  89.     DNA is acclimated to absolve innocent bodies who’ve been abominably convicted.
  90.     Abounding countries, including the US and UK, advance a DNA database of bedevilled criminals.
  91.     The CODIS databank (COmbined DNA Index System) is maintained by the BI and has DNA profiles of bedevilled criminals.
  92.     Polymerase alternation acknowledgment (PCR) is acclimated to amplify a sample of DNA so that there are added copies to analyze.
  93.     We eat DNA every day.
  94.     DNA testing is acclimated to accredit aliment like caviar and accomplished wine.
  95.     DNA is acclimated to actuate the abstention of crops.
  96.     Genetically adapted crops accept DNA from addition animal amid to accord the crops backdrop like annoyance resistance.
  97.     Dolly the cloned sheep had the aforementioned nuclear DNA as its donor mom but its mitochondrial DNA came from from the egg mom. (Does that accomplish any sense?)
  98.     Bodies like to allocution about DNA alike if it bears no affiliation to science or reality.
  99.     A accumulation of bloggers who address consistently about DNA and analysis accept affiliated to gether to anatomy The DNA Network.
  100.     Lists about DNA can get a little boring.
