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.
Recombinant DNA technology (rDNA) is technology that is used to cut a known DNA sequence from one organism and introduce it into another organism thereby altering the genotype (hence the phenotype) of the recipient. The process of introducing the foreign gene into another organism (or vector) is also called cloning.solation of the gene (DNA sequence) The technique involved in recombinant DNA technology is to slice (cut) the desired DNA segment and introduce it into a vector (e.g., plasmid).
