We yu de wach teledrama ɔ fim bɔt kriminal invɛstishɔn na TV, yu go dɔn yɛri dayalɔg lɛk "Na we di DNA ripɔt kam nɔmɔ wi go se ɛksaktɔli udat na di kriminal," nɔto so? Sɔntɛnde, yu go dɔn si na nyuspepa se dɛn bin no pɔsin we dɔn day sɔm ia afta dat bay we dɛn du DNA tɛst. Wetin na DNA finga prɛnt we ɔlman de tɔk bɔt? Tide, wi go tɔk bɔt dis wɔndaful teknɔlɔji we go ebul fɔ no pɔsin jɔs lɛk finga prɛnt, bɔt wit ivin mɔ prɛsishɔn ɛn kɔrɛkt.
Di ‘jɛnɛtik map’ we de insay wi bɔdi
Fɔ tɔk am simpul wan, DNA na smɔl smɔl tin dɛn we de insay ɛvri sɛl na wi bɔdi. Jɔs lɛk di bluprint fɔ bil os, ɔl di infɔmeshɔn we wi bɔdi nid fɔ gro, divɛlɔp, ɛn wok fayn fayn wan de afta de, dɛn rayt am na dis DNA as kɔd. Di ful nem fɔ DNA na dioxyribonukleic acid .
dis chen fכ DNA na 4 tכp kεmikכl kכmpawnd dεm. Wi de kɔl dɛn wan ya ‘bases’. dis dεm kin kam togεda tu tu fכ fכm ‘bεys pe’. Yu kin imajin, na lɛk 3 bilyɔn pan dɛn pe dɛn ya de insay jɔs wan sɛl na wi bɔdi! Di ɔda we aw dɛn tin ya jɔyn togɛda de tɛl wi sɛl dɛn aw fɔ mek nyu sɛl dɛn we fiba.
dis komplit sεt fכ DNA na wi bכdi dεn kכl am di ' jεnom ' . Na dis na di wɔndaful tin. כl mכtalman na di wכl gεt 99.9% pan in jεnom we di sem. Yes, yu DNA ɛn di wan fɔ pɔsin we yu nɔ no na 99.9% di sem. Bɔt da smɔl 0.1% difrɛns de na in mek mi ɛn yu difrɛn pan bɔdi ɛn maynd. Nɔto jɔs wi skin kɔlɔ , di we aw wi ia tan, di ayt, bɔt na dis smɔl difrɛns de sho aw wi kin gɛt sɔm sik dɛn .
DNA finga printin tεknכlכji de yuz kεmikכl dεm fכ separet dεn DNA strεn dεm ya εn fכ no di pat dεm we yu nכ de fכ yu, we difrεn 0.1%. Di ɛnd rizulyt na wan strɛp patɛn. dis patεn kin kכmpεr wit wan patεn we dεn gεt frכm כda DNA sεmpl.
So aw yu go gɛt DNA finga prɛnt?
Dis nɔto tin we kɔmplikt ɔ we de mek pɔsin fred lɛk aw yu go tink. Dis tɛst nid fɔ tek sɔm sɛl dɛn frɔm yu bɔdi.
- Insay di mɔt: Yu kin yuz swab fɔ skrap insay di mɔt frɔm di sayd we yu de chɛk.
- Skin: Na rili smɔl pat pan di skin.
- Frɔm di ia: wan rut fɔ wan tik we gɛt ia.
- Di wata we de kɔmɔt na di bɔdi: Frɔm di saliva, swet, ɔ ɔda wata we de na di bɔdi.
Bɔt i pas ɔl dɛn we yaDi we we izi ɛn we dɛn kin yuz mɔ na fɔ tek blɔd sɛmpul.
Wetin kin apin na di lab da tɛm de na jɔs dis:
1. DNA isolation: dεn ad kεmikכl dεm to di sεmpl fכ separet di DNA frכm di sεl dεm we de insay.
2. DNA kכt: nεks, כda kεmikכl prכsεs de brok dεn lכng DNA chen dεm ya insay di spεsifi k ripit pat dεm we wi nid. Dis na di pat dɛn we kin difrɛn frɔm wan pɔsin to ɔda pɔsin.
3. Fɔ mek kɔpi: Naw dɛn kin kɔpi dɛn smɔl smɔl DNA ya bɔku bɔku tɛm, we min se dɛn kin mek dɛn bɔku bɔku kɔpi dɛn, ɛn dɛn kin saiz bɔku. Dɔn i kin izi fɔ tɛst.
4. fכ no di pat dεm: nεks, dεn de put dεn DNA fragmεnt dεm ya insay wan mεdiכm we lεk jel εn dεn pas wan ilektrikal kכrant tru am. afta dat di DNA fragmεnt dεm de sεparayt to big εn sכm pat dεm bay dεn saiz εn muv tru di jel.

We wi dɔn, wi kin gɛt wan patɛn we gɛt strɛp dɛn, jɔs lɛk di barɔd we de na supamakit prɔdak. dis patεn na yu yכnik 'DNA finga prεnt'. dis kin kכmpεr wit wan patεn frכm כda pכsin in sεmpl wit 100% akכda.
Wetin na di rial bɛnifit dɛn we pɔsin kin gɛt we i de yuz DNA finga prɛnt?
Frɔm di de we dɛn kam fɔ no dis teknɔlɔji insay 1984, di bɛnifit dɛn we i de gi dɔn bɔku wan bay wan. Wi kin sheb di bɛnifit dɛn we i kin gɛt mɔ to tu pat.

Yu tink se i pɔsibul fɔ no bifo tɛm bɔt famili sik?
Yɛs, dis na rili impɔtant we fɔ yuz DNA tɛknɔlɔji fɔ mɛn pipul dɛn. Sɔm sik dɛn de we kin pas frɔm jɛnɛreshɔn to jɛnɛreshɔn tru jin. Fɔ ɛgzampul, sɔm kayn kansa (brɔst, ovarian, kɔlon kansa), at sik, ɛn sik dɛn lɛk Thalassemia , we kɔmɔn na wi kɔntri.
