I-Chromosome

Ama-Chromosomes yizakhiwo ezitholakala maphakathi (i-nucleus) yamaseli ezithwala izingcezu ezinde ze-DNA. I-DNA yinto ephethe izakhi zofuzo. Kuyindawo yokwakha umzimba womuntu.

Ama-Chromosomes aqukethe namaprotheni asiza i-DNA ukuthi ibe sesimweni esifanele.

Ama-chromosomes eza ngababili. Imvamisa, iseli ngalinye emzimbeni womuntu linamabhangqa angama-23 ama-chromosomes (ama-chromosomes angama-46 esewonke). Uhhafu uvela kumama; enye ingxenye ivela kubaba.

Ama-chromosomes amabili (i-X ne-Y chromosome) anquma ubulili bakho njengowesilisa noma owesifazane lapho uzalwa. Babizwa ngokuthi ama-chromosomes ocansi:

• Abesifazane banama-chromosomes ama-2 X.
• Abesilisa bane-1 X ne-1 Y chromosome.

Umama unikeza ingane i-X chromosome. Ubaba angafaka i-X noma u-Y. I-chromosome evela kubaba iyona enquma ukuthi ngabe ingane izalwa njengowesilisa noma owesifazane.

Ama-chromosomes asele abizwa ngama-chromosomes e-autosomal. Baziwa njengamabili we-chromosome 1 kuye ku-22.

• Ama-Chromosomes ne-DNA
