Study Notes
- In a human genome of 3 billion letters, even a small percentage difference can lead to millions of distinct lettering variations.
- Polymerase chain reaction is a technique used to amplify specific DNA sequences and detect minimal amounts of bacteria in a sample, eliminating the need for bacterial culture.
- Genetic tests help in understanding the development and transfer of antimicrobial resistance by bacteria due to mutations that can alter phenotypic characteristics.
- Plasmids are self-replicating DNA molecules located in the cytoplasm, capable of being transferred between bacterial species through conjugation, contributing to drug resistance acquisition.
- Mobile genetic elements like insertion sequences (IS) can move within bacterial chromosomes, disrupting genes and leading to observable changes like loss of certain characteristics.
