How to Use the NCBI's Bioinformatics Tools and Databases

This video tutorial introduces the NCBI bioinformatics tools and databases, guiding users on how to navigate the NCBI website to search for specific genes and proteins. It covers how to analyze gene variants and mutations, access GenBank records, and use tools like Blast for sequence comparison. The tutorial also explains how to explore gene records, protein information, and gene variants, providing insights into genomic research and data analysis.
