Question

Chromosomes occupy nonrandom radial positions, or [____], in relation to the center of the nucleus. Some chromosomes are preferentially internal, others are peripheral, and others are intermediate. The position of genes within the nucleus has been linked to their [____], and certain genes relocate to the [____] periphery after activation, and others relocate to the interior following activation. Active genes on [____] chromatin loops can co-localize with other active genes on other chromosomes, as shown by the example of the charged [____] receptor facilitating interchromatin contacts for coordinated gene expression in response to the hormone.

Please pick one.

(1) 30 nm fibers; activation; chromosome; condensed; vasopressin

(2) chromosome arms; repression; cellular; 30 nm fiber; estrogen

(3) territories; activity; nuclear; decondensed; estrogen

(4) regions; expression; nuclear; condensed; -factor

(5) expression territories; inactivity; chromatin; decondensed; -factor

Explanation / Answer

(3) territories; activity; nuclear; decondensed; estrogen

Chromosomes occupy nonrandom radial positions, or [__territories__], in relation to the center of the nucleus. Some chromosomes are preferentially internal, others are peripheral, and others are intermediate. The position of genes within the nucleus has been linked to their [_activity___], and certain genes relocate to the [_nuclear___] periphery after activation, and others relocate to the interior following activation. Active genes on [_decondensed___] chromatin loops can co-localize with other active genes on other chromosomes, as shown by the example of the charged [_estrogen___] receptor facilitating interchromatin contacts for coordinated gene expression in response to the hormone.
