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.
In order to claim a qualifying child, a taxpayer can't be eligible to be claimed as a dependent by anyone else. The child may be married, but if she is, she can't file a joint return unless it's to have withheld tax refunded and neither she nor her spouse may claim a personal exemption.
