How did eukaryotic genomes evolve?4 answersEukaryotic genomes evolved through a combination of symbiotic interactions, lateral gene transfer, and genome rearrangements. The origin of eukaryotes involves a symbiosis between Alphaproteobacteria and archaea, as supported by recent studies. The eukaryotic genome is a mosaic of genes from eubacteria, archaea, and unique eukaryotic genes, which may have been acquired through lateral gene transfer over time. The evolution of genomes is not a slow process but can involve various transformations, including the impact of transposable elements on genomes. The plant cell's integrated genome, consisting of nucleus/cytosol, plastids, and mitochondria, originated from endosymbiotic events and underwent complex restructuring and intermixing of genetic potentials, as well as lateral gene transfer. The eukaryotic nuclear genome likely descends from a specific archaea group, while the mitochondrial genome descends from alpha-proteobacteria.
DNA SEQUENCING First generation sequencing?4 answersFirst generation DNA sequencing refers to the initial method of sequencing DNA, developed by Frederick Sanger and his colleagues. It is considered the traditional method and involves chain termination sequencing using the dideoxynucleotide procedure. This method is commonly used to sequence DNA fragments containing one to a few genes as well as entire genomes from different organisms. The development of automation technology has greatly increased the throughput and reduced the cost of first-generation sequencing, making it still useful for many applications. However, with the advancement of technology, new generations of sequencing have been introduced, such as second-generation sequencing (NGS) and third-generation sequencing (TGS). These newer generations have higher throughput, reduced costs, and the ability to sequence individual nucleic acids directly. The recent advances in DNA sequencing technology have transformed the field of genomics and clinical diagnosis, with next-generation sequencing (NGS) and third-generation sequencing being widely used in disease diagnostics, pathogen detection, and genetic mutations.
How has antibiotic resistance evolved over time?5 answersAntibiotic resistance has evolved over time, with the emergence of multidrug-resistant pathogens and the drying up of the antibiotic pipeline. The problem of resistance evolution has been observed since the early days of antibiotics, and the introduction of each antimicrobial has resulted in resistance evolution in target and nontarget microbes. The evolution of antibiotic resistance is accelerating over time, as seen in both antibiotics and antifungals. The reliability of the commonly presented data on resistance emergence is questionable, as finding the original data for antibiotics has been difficult. However, for antifungals, the pattern of accelerating resistance evolution still holds. The causes of accelerating resistance evolution may include an increase in usage, increase in surveillance, and evolutionary dynamics such as cross-resistance and concurrent selection. Antibiotic resistance is a global health problem that requires integrative analytic tools and the accurate integration of -omic information into computational models. The crisis of antibiotic resistance necessitates urgent action and the development of new antibiotics through drug discovery.
