Genomics is a branch of genetics that applies methods like recombinant DNA, DNA sequencing, and bioinformatics to sequence, assemble, and research the function and structure of genomes. It involves research to analyze even the most complex biological systems. It is also involved in evaluating the entire DNA sequence of organisms and fine-scale genetic mapping. Open access is a set of principles and a range of practices through which research outputs are distributed online, free of cost, or other access barriers. With open access strictly defined, or libre open access, barriers to copying or reuse are also reduced or removed by applying an open license for copyright.
