This interesting genome sequencing approach ushered a new era of discoveries in microbial biology. Unlike the old genomics, metagenomics transcends boundaries by allowing scientists to explore the genetic complexities of all microbial communities more effectively and comprehensively.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Metagenomics\u00a0<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Metagenomics means the study of genetic material of microbes in their natural habitat. The process involves directly extracting and sequencing <a href=\"https:\/\/vajiramandravi.com\/upsc-exam\/dna\/\" target=\"_blank\"><strong>DNA<\/strong><\/a> or <a href=\"https:\/\/vajiramandravi.com\/upsc-exam\/rna\/\" target=\"_blank\"><strong>RNA<\/strong><\/a> from environmental samples in order to build a genome dataset that represents the collective genetic content of the whole microbial community in a given environment.\u00a0<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Metagenomics vs Traditional Genome Sequencing\u00a0<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Traditional genome sequencing requires culturing or isolating microbial species individually before decoding their genomes and limiting the focus to single organisms.
