For each of the following classifications, indicate whether you would expect to find an actively transcribed gene in the first category (1) or the second (2). Your answer would be a six-digit number composed of digits 1 and 2 only, e.g. 222121.
( ) 1: Heterochromatin, or 2: euchromatin
( ) 1: Chromosome puffs, or 2: condensed chromosome bands
( ) 1: Nuclear periphery, or 2: the center of the nucleus
( ) 1: Within the chromosome territory, or 2: extended out of the territory
( ) 1: Apart from, or 2: close to actively transcribed genes within the nucleus
( ) 1: 11-nm "beads-on-a-string" fibers, or 2: 30-nm fibers

More open chromatin is usually associated with higher transcriptional activity. Thus, an actively transcribed gene is likely to be found in euchromatin (which is generally not associated with the nuclear lamina), and more so in the extended 11-nm fibers. In a polytene chromosome, "puffs" represent the sites where active transcription occurs. An active gene can even leave the territory of its parent chromosome and extend out into "factories" of transcription along with other active genes.
