Bioinformatics Accessing NCBI databases and tools with Biopython [Entrez]

#12daysofbiopython In Day 2 of 12 days of Biopython video I am going to show you how to access and query NCBI's databases using Biopython which provides interface to Entrez, data retrieval system. I am going to show you how to get a list of all databases available through Entrez and how to seach and fetch specific records. I am going to show you how to query nucleotide databases to find a sequence of specific gene from specific organism.
