| First, many heterochromatic genes have large introns relative to the genome as a whole. |
| This light contributes homochromatic and heterochromatic components and will include single and multiple scattered components. |
| Global reorganization of chromatin into heterochromatic foci is a hallmark of senescent cells. |
| In wild-type chromosomes, these proteins are confined to the heterochromatic DNA sequences either by terminator sequences or by proximally directed initiators. |
| This phenomenon is discussed in light of a possible role of heterochromatic proteins in the process of heterochromatin underrepresentation in polytene chromosomes. |
