Yu na pɔsin we de wach kraym drama ɛn fim dɛn na TV? Dɔn yu go mɔs dɔn rili sabi wɔd dɛn lɛk ‘DNA test done’ ɛn ‘DNA match’. Bɔt wetin rili na DNA Finga Prɛnt? Na sɔntin we dɛn jɔs de yuz fɔ kech kriminal dɛn? Nɔ, na wɔndaful tɛknɔlɔji we impɔtant fɔ bɔku tin dɛn pas dat. Lɛ wi tɔk bɔt am jɔs tide.
Wetin na dis ‘jɛnɛtik map’ we de insay wi bɔdi?
Fɔ tɔk am simpul wan, DNA Fingerprinting na kemikal tɛst we de sho di jenɛtik we pɔsin ɔ ɛnitin we gɛt layf gɛt. Fɔ ɔndastand dis, wi nid fɔ no fɔs wetin na DNA.
Di wɔd DNA na shɔt fɔ dioxyribonukleic acid . I de insay ɛvri sɛl na yu bɔdi. Tink bɔt am as di bluprint fɔ yu wan ol layf.
dis DNA chen na 4 kayn kεmikכl kכmpawnd dεm. Wi de kɔl dɛn wan ya ‘bases’. dis dεm kin kam togεda tu tu fכ fכm ‘bεys pe’. Na lɛk 3 bilyɔn pan dɛn pe dɛn ya de na yu DNA! Di ɔda we aw dɛn tu tu dɛn ya jɔyn togɛda de tɛl yu sɛl dɛn aw fɔ mek kɔpi fɔ dɛnsɛf.
Dis ɔl sɛt ɔf kemikal kɔmpawnd dɛn na wetin wi kɔl di ‘jinom.’ Dis na yu kɔmplit jenɛtik infɔmeshɔn ripɔsitɔri.
di amazing tin na dat di genome fכ eni pכsin na di wכl na 99.9% idεntikal. Bɔt da smɔl smɔl 0.1% difrɛns we lɛf na in de mek yu difrɛn frɔm mi pan bɔdi ɛn maynd, ɛn mi frɔm ɛni ɔda pɔsin. Di we aw wi de luk, di we aw wi de biev, di we aw wi de tink, di we aw wi kin gɛt sɔm sik dɛn, ɔl dɛn tin ya kin afɛkt dis smɔl difrɛns. DNA Fingerprinting tεknכlכji de yuz kεmikכl dεm fכ separet di DNA strεnd dεm εn pul dεn 0.1% fragmεnt dεm we yunik fכ yu. Wi de si da rizɔlt de as patɛn fɔ layn dɛn. Wi kin kɔmpia da patɛn de wit ɔda ɛgzampul.

Wetin kin apin na di lab?
Afta dɛn dɔn tek di sampul frɔm yu, dɛn kin sɛn am na di lab. Na dis na wetin kin apin:
1. DNA isolation: fכs, dεn ad kεmikכl dεm fכ separet כnli di DNA frכm di sεl dεm na yu sεmpl. Dɔn, dɛn kin sɔlv di DNA insay wata.
