Locus-control regions are trans-acting gene regulatory sequences. A.True B.False

Understand the Problem

The question is asking whether locus-control regions are considered trans-acting gene regulatory sequences, requiring knowledge of genetic terminology and concepts.

More Information

Locus control regions are defined by their ability to enhance the expression of linked genes to physiological levels, and are considered cis-regulatory elements rather than trans-acting, as they affect genes on the same chromosome.

Tips

A common mistake is confusing cis-regulatory elements, which act on genes on the same chromosome, with trans-acting factors, which can affect genes on different chromosomes.
