DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

AI approach reveals possible fusion of rare diseases in COVID-19 origins

Despite extensive research, the origins of COVID-19 remain elusive. In a new study published in the KeAi journal Advances in Biomarker Sciences and Technology (ABST), an AI-driven approach was adopted to examine DNA methylation patterns at 865,859 CpG sites in blood samples from early COVID-19 patients.
