The lac repressor is made up of four identical polypeptides (thus a homotetramer). Part of the molecule has a site (or sites) that enable it to recognize and bind to the 24 base pairs of the lac operator. Another part of the repressor contains sites that bind to allolactose.
A âdependentâ is identified from the relationship between the parent and the child. It includes any child up to the age of 26, whether that child is married, a student, is employed, and/or has coverage available through a non-parent.** Spouses and children.
If you lived with your parents for more than half the tax year, for instance, they are generally entitled to claim you as a dependent; but if you got married during the year or primarily supported yourself, you're entitled to the exemption, which removes your parents' right to claim you.
