DNA quality is typically assessed through several parameters, including its concentration, purity, and integrity. Methods such as spectrophotometry, gel electrophoresis, and fluorometry are commonly used. High-quality DNA should have an A260/A280 ratio between 1.8 and 2.0 and show minimal degradation in electrophoresis. These assessments ensure that the DNA is suitable for downstream applications like sequencing, PCR, and cloning.
