본문내용

• STR: repeated sequences of 3-5 base pairs (loci) which can be identified in a known data base.
• Very useful in DNA analysis because they show great variability among individuals.
• Newer and more precise method yielding errors of about 1 in 1029.
• Does not require very much DNA, can be coupled with PCR.
• Short tandem repeat (STR) technology : evaluates specific regions (loci) that are found on DNA.
• The variable (polymorphic) nature of STR regions intensifies the discrimination between one DNA profile and another.
