Explanation:
Detailed explanation-1: -Viral remnants make up 8 percent of the human genome, and a new study finds that these sequences are still active in healthy people.
Detailed explanation-2: -In contrast to eukaryotes, prokaryotes have evolved highly optimized genomic systems with advanced mechanisms for both DNA gain and loss [3]. Moreover, approximately 90% of bacterial genomes consist of genes [2, 3] compared to 1–2% in mammals [39, 40].
