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.
When transcription is arrested by the presence of a lesion in the transcribed strand of a gene, DNA repair proteins are recruited to the stalled RNA polymerase to initiate a process called transcription-coupled repair.
