Макронукле́ус, или вегетати́вное ядро́ — крупное ядро клеток инфузорий. В интерфазе именно в этом ядре происходят процессы транскрипции РНК, значит, макронуклеус управляет жизнедеятельностью неделящейся клетки. Википедия
a relatively large densely staining nucleus of most ciliate protozoans that is derived from micronuclei and controls various nonreproductive functions. |
The macronucleus, which is usually highly polyploid, divides amitotically during asexual reproduction and controls mainly somatic functions (e.g. RNA synthesis) ... |
Macronucleus definition: the larger of the two types of nuclei occurring in ciliate protozoans, having a multiple set of chromosomes and functioning in cell ... |
The macronucleus provides the nuclear RNA for vegetative growth. Mating cells exchange haploid micronuclei, and a new macronucleus develops from a new diploid ... |
