Yini i-plasmid

I-plasmid yi-molecule encane ye-DNA eyindilinga etholakala kumagciwane nezinye izinto eziphilayo ezincane ze-.plasmids zihlukaniswe ngokomzimba kusuka ku-chromosomal DNA bese ziphindaphindeka. Ngokuvamile banenombolo encane yohlobo lwezakhi zofuzo - ikakhulukazi, abanye abahlotshaniswa nokumelana namagciwane - futhi bangadluliswa besuka kwesinye iseli baye kwelinye.

I-Plasmid ingenye yezinyathelo ezibalulekile ekukhiqizweni kwezidakamizwa ze-cell ezifana nemoto - amaseli we-T, okubandakanya izinqubo eziyinkimbinkimbi njengokukhiqizwa, ukuhlanzwa kanye nokuhlaziywa.

Ukulawulwa kwekhwalithi yobuchwepheshe be-plasmid

Ukulawulwa kwekhwalithi kobuchwepheshe be-plasmid kuyinqubo ebalulekile yokuqinisekisa ukuthi ama-plasmid akhiqizwayo ahlangabezana nenhloso ehlosiwe futhi ephephile, esebenzayo futhi engaguquki. Izinto zokulawula ezisezingeni le-plasmid zobuchwepheshe ikakhulukazi ezifaka inani le-PH, ukubukeka, ukukhomba ukugxila / okuqukethwe, 260/280, isilinganiso se-Cell RNA, i-cell cell cell, i-cell cell celte, njll.
