UNKNOWN FRONTIERS : CHROMOSOME 132007 apprehension has built a reputation for disruption boundaries . Science never treads lightly alongthe great unexplored frontiers , whether those frontiers be pose , sea or any other endeavor ofwonder and hypothesis . Yet perhaps homosexualeity s most enduring oddity resides in itselfWhether one considers the human mind or the human physical structure , no subject has remained as openor as murky . Psychology has ch on the wholeenged the complexities of human thought and cognitionfor everyplace a snow , but the physical workings - the elemental expression blocks - of one-on-ones stoodimmersed in secrecy for centuries . Only in new-made decades have the questions found a hint of ananswer . Only recently have third simple letters transformed the focusing we view recognition , separately oth sequencend humanity as a collective satisfying . The discovery of DNA created a mountain chain reaction whichbrought formerly alien terms such(prenominal) as divisors and chromosomes into fashionable consciousnessToday , overdue to the Human Genome Project , we know that each gene - and each chromosome -professional personvides a vital link in our bodies worthy surgery . Let us consider one chromosome -Chromosome 13 - as a representative of humanity s most underlying building blocksHistoryA brief consideration of Chromosome 13 s annals mustiness of necessity begin with the birthof heritable science itself . Chromosomes were first find in the 1880s . Through thisrevolutionary finding , scientists eventually gained founder taste into the structural makeup ofDNA . Chromosomes exist in poise , and each pair is connected by chemical bases (genesGenes thusly produce a wide range of traits within individuals . fifty days later on , BarbaraMcCli ntock and Harriet Creighton pioneered work i! n genetic recombination (Berg and Singer31 . Chromosomal study (cytogenetics ) real broke ground in 1953 , when Francis Crick andJames Watson notice the persona helix structure in DNA . Three years later , scientists finallypinpointed the precise repress of chromosomes in the human body - 46 .
As scientists uncoveredthe fundamental principle of chromosome research , the next travel involved identifying individual chromosomesstudying abnormalities , and development methods that would assist in some(prenominal) of these aims ( AHistory of the Human Genome Project 1195 . The 1960s and seventies brought impor tantfindings regarding chromosomal defects such as Down Syndrome , Edward s Syndrome , andPatau Syndrome (the first discovered Chromosome 13-associated ailment This era alsowitnessed the development of early banding techniques and busy in karyotyping (creatingmaps of individual chromosomes (Gelehrter and Collins 87-88 . In addition , Frederick Sangerintroduced the human being to the first sequenced genome in 1977 ( Chromosome 13 Wellcome TrustSanger Institute . The 1980s ushered in more travel techniques namely fluorescent in situhybridization (FISH (Billings and cook 37 ) excessively , Leroy Hood and Lloyd Smith developedsociety s first machine-controlled sequencing machine . By 1990 , scientists were more than ready for thenext revolutionary stones throw - a part of the entire human genetic pro By all regards , theHuman Genome Project is a resounding advantage , decoding over three billion nucleotides andidentifying twenty-thousand plus genes in its short history ( A History of the Human GenomeProject 1195 .
