In contrast, the macronucleus serves as the somatic nucleus, divides amitotically, contains multiple copies of most genes, and is transcriptionally active. |
In contrast, the somatic macronucleus is polyploid, divides amitotically, and is actively transcribed. |
A round macronucleus with one micronucleus is in the anterior half of the body. |
The macronucleus is usually dorsal, elliptical, and cleft, with one micronucleus attached. |
As a result, the normal complement of DNA in the micronucleus is 4C during the amitotic division of the macronucleus and cytokinesis. |
The macronucleus is spherical, centrally placed, and with one micronucleus closely applied. |
