Chromosome Number 13

UNKNOWN FRONTIERS : CHROMOSOME 132007 scientific discipline has built a genius for breaking boundaries . Science never treads lightly alongthe great unexplored frontiers , whether those frontiers be billet , sea or any other object ofwonder and surmisal . Yet perhaps valetity s around steadfast specialness resides in itselfWhether wholeness considers the human mind or the human clay , no subject has remained as openor as shadowy . Psychology has ch solelyenged the complexities of human thought and cognitionfor all over a snow , but the physical workings - the basic put on blocks - of singles stoodimmersed in secrecy for centuries . Only in recent decades have the questions free-base a hint of ananswer . Only tardily have terce simple letters transformed the right smart we view information , each(prenomin al) othearned run averagend humanity as a collective totally . The discovery of deoxyribonucleic acid created a chain reaction whichbrought one time alien terms much(prenominal) as genes and chromosomes into popular consciousnessToday , imputable to the Human Genome Project , we know that all(prenominal) gene - and each chromosome -provides a vital link in our bodies proper performance . Let us consider one chromosome -Chromosome 13 - as a representative of humanity s most basic building blocksHistoryA brief consideration of Chromosome 13 s fib must inescapably begin with the birthof genetic science itself . Chromosomes were archetypical discovered in the 1880s . Through thisrevolutionary finding , scientists at long last gained better acuteness into the structural makeup ofDNA . Chromosomes exist in reduplicates , and each pair is connected by chemical bases (genesGenes thence produce a wide range of traits within individuals . liter days afterward , Barbara McClintock and Harriet Creighton pioneered w! ork in genetic recombination (Berg and Singer31 . chromosomal study (cytogenetics ) authentically broke ground in 1953 , when Francis wrick andJames Watson discovered the two-bagger helix structure in DNA . Three years later , scientists finallypinpointed the precise number of chromosomes in the human body - 46 . As scientists uncoveredthe basics of chromosome query , the next travel involved identifying individual chromosomesstudying abnormalities , and developing methods that would attention in some(prenominal) of these aims ( AHistory of the Human Genome Project 1195 . The 1960s and 1970s brought importantfindings regarding chromosomal defects such as Down Syndrome , Edward s Syndrome , andPatau Syndrome (the send-off discovered Chromosome 13-associated complaint This era alsowitnessed the development of early banding techniques and interest in karyotyping (creating mappings of individual chromosomes (Gelehrter and Collins 87-88 . In addition , Frederick Sangerint roduced the world to the first sequenced genome in 1977 ( Chromosome 13 Wellcome TrustSanger Institute . The 1980s ushered in more(prenominal) ripe(p) techniques namely fluorescent in situhybridization (FISH (Billings and Brown 37 ) excessively , Leroy Hood and Lloyd Smith developedsociety s first automated sequencing machine . By 1990 , scientists were more than ready for thenext revolutionary step - a map of the entire human genetic pro By all regards , theHuman Genome Project is a resounding success , decoding over three billion nucleotides andidentifying twenty-thousand plus genes in its short write up ( A History of the Human GenomeProject 1195 .
