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 general, dependents are exemptions that reduce a taxpayer's taxable income. Taxpayers typically can take an exemption for each of his or her dependents. Spouses are not considered dependents from a tax perspective. To claim someone as a dependent, the dependent must be a U.S. citizen, a U.S. resident alien, a U.S. national resident, or a resident of Canada or Mexico for some part of the year. Adopted children have some special exceptions to this rule. The filer must provide Social Security numbers for all dependents.
