Too many people, not enough windows,* and regardless of any seeming spaciousness, I always feel claustrophobic. Books like Dayna Lorentzâs No Safety in Numbers make me feel even more satisfied with my mall-free lifestyle. Read the last Bookshelves of Doom on the paranormal thriller 'Dreamless.'. When a suspicious-looking device is found clipped to a ventilation shaft, the West Nyack Mall is locked down within an hour.
DNA profiling (also called DNA fingerprinting, DNA testing, or DNA typing) is a forensic technique used to identify individuals by characteristics of their DNA.he system of DNA profiling used today is based on PCR and uses simple sequences or short tandem repeats (STR). This method uses highly polymorphic regions that have short repeated sequences of DNA (the most common is 4 bases repeated, but there are other lengths in use, including 3 and 5 bases).
A DNA microarray (also commonly known as DNA chip or biochip) is a collection of microscopic DNA spots attached to a solid surface.Scientists use DNA microarrays to measure the expression levels of large numbers of genes simultaneously or to genotype multiple regions of a genome.Each DNA spot contains picomoles (10 â12 moles) of a specific DNA sequence, known as probes (or reporters or oligos).NA microarrays can be used to detect DNA (as in comparative genomic hybridization), or detect RNA (most commonly as cDNA after reverse transcription) that may or may not be translated into proteins. The process of measuring gene expression via cDNA is called expression analysis or expression profiling.
