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.
A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.or example, some mutations alter a geneâs DNA sequence but do not change the function of the protein made by the gene. Often, gene mutations that could cause a genetic disorder are repaired by certain enzymes before the gene is expressed and an altered protein is produced.
