The transcription or the expression of a gene(the process by which the DNA sequence is converted into a functional product like protein or RNA) is controlled by the region of the DNA generally present upstream of the gene. This region consists of several short segments(also known as motifs) which act as binding sites to proteins [...]

I learnt about epistasis in twelfth year of schooling. It was first used by Bateson to describe the masking of one allele(variant of a gene) at a locus masking another allele at a different locus. But today I see this word used in different contexts and I was really confused about its meaning, so [...]
