Microblading is a form of semi permanent makeup that creates gorgeous and natural hair strokes to reshape or fill in your eyebrows. The hair strokes are created with a handheld microblade, unlike traditional eyebrow tattoo, which uses a machine.
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.
