Mayelana nalolu hlelo lokusebenza

I-Genetics iwucwaningo lwezakhi zofuzo futhi izama ukuchaza ukuthi ziyini nokuthi zisebenza kanjani. Izakhi zofuzo ziyindlela izinto eziphilayo ezizuza ngayo izici noma izici kokhokho bazo; ngokwesibonelo, izingane ngokuvamile zifana nabazali bazo ngenxa yokuthi zizuze ufuzo lwabazali bazo. I-Genetics izama ukukhomba ukuthi yiziphi izici ezitholwa njengefa, futhi ichaze ukuthi lezi zimpawu zidluliselwa kanjani ezizukulwaneni ngezizukulwane.

Izakhi zofuzo ziyizingcezu ze-DNA eziqukethe ulwazi lokwenziwa kwama-ribonucleic acid (RNAs) noma ama-polypeptides. Izakhi zofuzo zitholwa njengeyunithi, abazali ababili behlukanisela izingane zabo amakhophi ezakhi zabo zofuzo. Abantu banamakhophi amabili ofuzo ngalunye, kodwa iqanda ngalinye noma ingqamuzana lesidoda lithola kuphela elinye lalawa makhophi kufuzo ngalunye. Iqanda nesidoda kuhlangana ukwakha iqoqo eliphelele lezakhi zofuzo. Inzalo etholakalayo inenani lezakhi zofuzo elilinganayo nelabazali bayo, kodwa kunoma isiphi isakhi sofuzo, ikhophi eyodwa kwezimbili ivela kubaba, nenye ivela kunina.

Izakhi zofuzo
izakhi zofuzo, ukufunda ngofuzo ngokujwayelekile kanye nofuzo ikakhulukazi. I-Genetics yakha enye yezinsika eziyinhloko zebhayoloji futhi igqagqene nezinye izindawo eziningi, njengezolimo, imithi, kanye ne-biotechnology.

Izihloko ezifakwe kuhlelo lokusebenza zinikezwe ngezansi:
- Izindaba zofuzo/amabhulogi
- Amaseli ofuzo kanye ne-DNA
- Impilo kanye nezinhlobonhlobo
- Indlela izakhi zofuzo ezisebenza ngayo
- Ukuthola isimo sofuzo
- I-Genetics kanye nezici zomuntu
- Ukubonisana Ngezofuzo
- Ukuhlolwa Kofuzo
- Okuqondile ekuhlolweni kofuzo lwabathengi
- Ukwelashwa kofuzo nokunye kusengaphambili kwezokwelapha
- Ucwaningo lwe-Genomic kanye nemithi enembile

I-Genetics ibizwa ngokuthi ucwaningo lokuqonda ukusebenza kofuzo lwezimpawu kusuka kubazali kuya enzalweni. Isisekelo ufuzo okuso saziwa ngokuthi ifa. Ichazwa njengenqubo lapho izici zidluliselwa kwesinye isizukulwane kuya kwesinye. U-Gregor Johann Mendel waziwa ngokuthi “Ubaba Wezakhi Zofuzo Zesimanje” ngokuthola kwakhe ezimisweni eziyisisekelo zofuzo.

Isakhi sofuzo siyiyunithi eyisisekelo ebonakalayo nesebenzayo yofuzo. Izakhi zofuzo zakhiwe yi-DNA. Ezinye izakhi zofuzo zisebenza njengeziyalezo zokwenza ama-molecule abizwa ngokuthi amaprotheni. Nokho, izakhi zofuzo eziningi aziwafaki amaphrotheni. Kubantu, izakhi zofuzo ziyahlukahluka ngobukhulu kusukela kumakhulu ambalwa esisekelo se-DNA kuya kwezisekelo ezingaphezu kwezigidi ezingu-2. Umzamo wokucwaninga wamazwe ngamazwe obizwa ngokuthi i-Human Genome Project, owasebenza ukuze kutholwe ukulandelana kwezakhi zofuzo zomuntu nokuhlonza izakhi zofuzo eziqukethe, ulinganisela ukuthi abantu banezakhi zofuzo eziphakathi kuka-20 000 nezingu-25 000.

Uma uthanda uhlelo lwethu lokusebenza sicela usinike isilinganiso sezinkanyezi ezinhlanu. Sisebenza kanzima ukwenza uhlelo lokusebenza lube lula futhi lube lula.
