Izvo zvinonziwo RFLP Analysis, iyo nzira inoshandisa mapirymorphisms mumarudzi evanhu ega genetic codes. Kunyange zvazvo nhengo dzose dzezvipenyu dzine zvinyorwa zvakafanana, maitiro akasiyana-siyana anokonzera kuchinja kwe phenotype, zvakadai sechitarisiko kana chemetabolism, pakati pevanhu.
RFLP: Analytical Technique uye Applications
RFLP tsanangudzo yekuongorora inosanganisira kuderedza imwe nzvimbo yeDNA nemhando yakasiyana-siyana inozivikanwa, nekudzivirira masimba enzymes, ndokuzoparadzanisa zvidimbu zveDNA ne agarose gel electrophoresis uye kusarudza huwandu hwezvimedu uye huwandu hwakaenzana.
Murairo muyemeyamu inonzi enzyme, puroteni molecule, iyo inoderedza DNA pane zvibvumirano zvekudzivirira. Muchidimbu, shanduro yeDNA inoputsika uye inopedzwa nemigumisiro yemakemikari. Zvitsva zvinokonzerwa zvakaparadzana maererano nekureba kwavo uye chimiro chezvikamu zvakasiyana zvichasiyana kune mumwe nomumwe akaedzwa.
Yese yakazara RFLP inoda kushandiswa kuongorora mazita, DNA kupatsanurwa, electrophoresis, kuvhara, kushandiswa, kushamba, uye kuzvinyora. Izvo zvakaonekwa kuti RFLP inotaridzirwa uchishandiswa X-rairi yefirimu mukutsvaga, apo DNA zvikamu zvinogona kuonekwa uye kuongororwa mushure mekunge zvakaparadzana kubva kune imwe neimwe ne electrophoresis.
Zvimwe zvekushandiswa kweRFLP kuongorora zvinosanganisira:
- DNA minprinting . Forensic masayendisiti angashandisa RFLP kuongororwa kuti aone vanhu vanofungidzirwa zvichienderana nehuwandu hwezvakaonekwa zvakakonzerwa pane zviitiko zvemhosva.
- Paternity. RFLP inoshandiswawo mukugadzirisa kwevana kana kuti kutevera madzitateguru.
- Genetic diversity. Iyo nzira inogona kushandiswa mukudzidza nekushanduka-shanduka nekufamba kwemhuka dzomusango, kudzidzira kubereka maitiro mumhuka dzevanhu uye mukuona uye kuongororwa kweimwe zvirwere.
Imwe nzira yekushandisa RFLP kuziva kwekusiyana kwemajini (genomes) chinhu chakakosha mu genome mapping uye genetic disease analysis. Kana nzvimbo yemumwe chirwere chegene iri kutsvaga mune imwe chromosome, zvino vatsvakurudzi vaizoongorora DNA yemhuri yemhuri ine chirwere, ezvo tsvaga maitiro akafanana ehaka muRFLP zvese.
Pane imwe chirwere chemajini chinowanikwa munzvimbo ino, kuitisa RFLP kuongororwa kune dzimwe nhengo dzemhuri kunogona kuzivisa mutakuri wemagenene anogadzirisa kana zviratidzo zvehutano hwehutano. Zvakakosha kucherechedza kuti nzira yeRFLP haina kunyanya kushandiswa ikozvino itsva, maitiro akasimba akawanda anoshandiswa kuDNA kuongororwa mune zvinyorwa zvesayenzi uye dzimwe mimwe minda.
Maonero Asina Hanya Ekuongorora
Zvinosuruvarisa, nzira yekuongorora yeRFLP inotyisa uye inononoka. Kunze kwekuda mari yakawanda yeDNA samuenzaniso - muenzaniso unowanzodikanwa kuva wakaenzana nehupamhi hwekota, iyo inenge yakakura kune DNA samples - iyo nzira, kubva pakuongorora mabhii ekushamba uye kuongorora, inogona kusvika kune mwedzi wakakwana kuti upedze.
Migumisiro inobva kuHuman Genome Project yakanyatsopindira kudiwa kweRFLP. Irojekiti yakabvumirwa kugadzirisa kuwirirana kwese kweDNA inowanika mumasero evanhu, gome revanhu, uye nekutsvaga mazita ose ejeni mumaromu evanhu.
