WebAbstract. All the self-reproducing cellular organisms so far examined have DNA as the genome. However, a DNA-less organism carrying an RNA genome is suggested by the fact that many RNA viruses exist and the widespread view that an RNA world existed before the present DNA world. Such a possibility is most plausible in the microbial world where ... WebThe human microbiome contains billions of bacteria, primarily found in the gut. Many of these bacteria are non-pathogenic and could have a beneficial relationship with our cells. One non-pathogenic species of interest is Streptococcus thermophilus for its frequent use in the dairy industry. To further understand these bacteria, we must study how they …
