Mechanism of dna uptake by bacteria
WebJun 11, 2024 · Natural transformation is a broadly conserved mechanism of horizontal gene transfer in bacterial species that can shape evolution and foster the spread of antibiotic resistance determinants,... WebDNA uptake in most systems is not sequence-specific. However, in some Gram-negative microorganisms,such as Haemophilus influenzae 12 and Neisseria species13,effi-cient uptake occurs only if a specific sequence is present, although the DNA binding is nonspecific.The sequence motifs that are required for efficient uptake,called DUS (DNA …
