Imfuza

Imfuza sisiqwengana esifutshane seDNA. Iimpawu zemvelo zixelela umzimba ukuba ungazakha njani iiproteni ezithile. Kukho malunga nama-20,000 emfuza kwiseli nganye yomzimba womntu. Ngokudibeneyo, benza iplani yomzimba womntu kunye nendlela esebenza ngayo.

Imvelo yomntu ebizwa ngokuba yi-genotype.

Imfuza yenziwa ngeDNA. Imicu ye-DNA yinxalenye yeekromosomes zakho. IiChromosomes zinamanani afanayo ekopi enye yohlobo oluthile. I-gene ivela kwindawo efanayo kwi-chromosome nganye.

Iimpawu zofuzo, ezinje ngombala wamehlo, zibalulekile okanye zigqithisile:

• Iimpawu ezibalaseleyo zilawulwa luhlobo olunye lwesibini kwii-chromosomes.
• Iimpawu ezihlaziyiweyo zifuna zombini izakhi zofuzo ukuze zisebenze kunye.

Iimpawu ezininzi zomntu, ezinjengokuphakama, zichongiwe ngaphezulu kwe-1 yemfuza. Nangona kunjalo, ezinye izifo, ezinjengearheng cell anemia, zinokubangelwa kukutshintsha kohlobo olunye.

• Chromosomes kunye neDNA
