Genomic data

Definition

Genomic data refers to the complete set of DNA within an organism, including its genes and non-coding sequences. This type of data is crucial for understanding the genetic makeup and variations that can influence biological functions, disease susceptibility, and evolutionary relationships. The analysis and interpretation of genomic data can provide insights into how organisms develop and adapt, as well as inform personalized medicine and agricultural improvements.
