Question

what conclusion CANNOT be made from two dna fingerprints that showidentical patterns of bands? a. the dna from the two dna fingerprints almost certainly camefrom the same person b. the dna from the two dna fingerprints definitely came fromtwo different people c. the dna from the two dna fingerprints were separated insize. d. the dna repeats that formed the bands in each dnafingerprint are the same length a. the dna from the two dna fingerprints almost certainly camefrom the same person b. the dna from the two dna fingerprints definitely came fromtwo different people c. the dna from the two dna fingerprints were separated insize. d. the dna repeats that formed the bands in each dnafingerprint are the same length

Explanation / Answer

The    answer   is   ( c)    if  it   exactly   means  that   the   DNA   from   the    two   DNA fingerprints are   separate   in   size .    It   is   because    DNA   finger  printing   is   a highly    reliable   method   for   solving  the    crime    mystery . Only    DNA  from     the   same   person   can show  same  banding   pattern   due to  very   high   specificity( identical twins   being the   exeptions ) .   For     forensic   studies    scientist   use    genetic marker   which is    a   particular   sequence   of   the   DNA    called    short   tandem   repeat ( STR)  , unique   to    every  individual , varying in the number of   repeats  & length . As    for  the    study    only this DNA   segment   is  amplified    using   PCR    technique   , therefore   size   of   the    DNA   cannot   be   determined.
