Genetic Variants and Bioinformatics Concepts

This video tutorial by Svenja Lohner from Science Buddies introduces the use of NCBI's bioinformatic tools and databases for genomic research. It covers navigating the NCBI website, searching for specific genes and proteins, accessing GenBank records, and analyzing sequences using the FASTA format. The tutorial also explores gene records, gene variants, and their significance, providing a comprehensive guide to using NCBI resources for genomic research.
