What is epigenetics?
Epigenetics, literally “on” genes, refers to all modifications to genes other than changes in the DNA sequence itself. Epigenetic…[阅读更多]
What are SNPs?
Single nucleotide polymorphisms or SNPs (pronounced “snips”) are DNA sequence variations that occur when a single nucleotide (A,T,C,or G) in the genome sequence is altered. For example a SNP […]
