Genes located in heterochromatin are transcriptionally silenced, irrespective of their own promoter sequences. |
|
In contrast, the macronucleus serves as the somatic nucleus, divides amitotically, contains multiple copies of most genes, and is transcriptionally active. |
|
These observations suggest that the cells in the pericycle of alloxan-treated plants are much more transcriptionally active than their control counterparts. |
|
After conjugation, chromosomes in the transcriptionally active macronucleus develop by fragmentation, elimination, and amplification of germ line chromosomes. |
|
Northern blot analysis has shown that M46 is expressed in G186AS and Downs strains, but is transcriptionally silent in G184AS and G217B strains. |

Characterization of sgk, a novel member of the serineAhreonine protein kinase gene family which is transcriptionally induced by glucocorticoids and serum. |
|
Interestingly, we found that survivin is transcriptionally downregulated and proteasome-degraded by TIIA in an array of TRAIL-resistant ovarian cancer cell lines. |
|
The extremely tight complexes formed by the interaction of spermatozoal DNA with proteins generate highly stable and transcriptionally inert chromatin. |
|
