Behaviors thought to be feminine or masculine differ from one culture to another and across time periods. Many artists have used their work to examine, question, and criticize the relationships between gender and society. As the feminist movement gained momentum in the 1960s and 1970s, artists began to challenge traditional roles of women, addressing topics such as women in domestic and public spheres, and the conventional standards of beauty.
DNA repair is a collection of processes by which a cell identifies and corrects damage to the DNA molecules that encode its genome.n contrast to DNA damage, a mutation is a change in the base sequence of the DNA. A mutation cannot be recognized by enzymes once the base change is present in both DNA strands, and, thus, a mutation cannot be repaired.
The DNA repair ability of a cell is vital to the integrity of its genome and thus to the normal functionality of that organism. Many genes that were initially shown to influence life span have turned out to be involved in DNA damage repair and protection.amage to DNA alters the spatial configuration of the helix, and such alterations can be detected by the cell. Once damage is localized, specific DNA repair molecules bind at or near the site of damage, inducing other molecules to bind and form a complex that enables the actual repair to take place.
