In this video I go over what are reference genomes, how are they build and what are some uses of having a reference genome. In addition, I talk about what are different builds (versions) of reference genomes i.e. GRCh38 (hg38)/GRCh37, what makes them different and which one should be used to perform genomics analysis.
I hope you find this video helpful! Leave your thoughts in the comment section below!
