Biotechnology - 15 With the use of biochips, researchers can compare an individual's single nucleotide polymorphisms* (SNPs), which to the standard from the human genome project, or another biochip, identifying how the individual differs from the standard. Most people have a SNP about one per thousand nucleotides. SNPs may be responsible for many genetic differences, from cystic fibrosis and sickle cell anemia to red hair and cholesterol levels. A database of perhaps 300,000 SNPs is being developed and may be a future way for physicians to screen most accurately for genetic diseases. Your biochip may also uniquely identify all that is you,

Unformatted text preview: genetically speaking. *Single nucleotide polymorphisms are similar to the short tandem repeats (STRs) used in forensics, but they are variations in a single nucleotide between different individuals, different population cohorts, or even one's homologous chromosomes. Microarray analysis is used in cystic fibrosis screening. Families in which cystic fibrosis is found can be screened to see which family members carry a cystic fibrosis allele. Microarrays can also be used in cancer screening, for example, to better target a specific treatment to a specific cancer, not just for finding a genetic profile....
