To retrieve a gene or protein sequence from NCBI, the first step is to visit the official NCBI website ([www.ncbi.nlm.nih.gov](http://www.ncbi.nlm.nih.gov)). On the homepage, you will find several databases and tools. For sequence retrieval, you typically start by using the NCBI Gene or NCBI Protein database. You can enter specific search terms, such as the gene or protein name, or the accession number if you know it. You can also use related keywords, species names, or other identifiers to narrow down your search. Once you search for the gene or protein of interest, you will be directed to a page containing the summary and detailed information about that sequence. On this page, you will find the actual sequence in a FASTA format, which you can copy or download. FASTA format is a text-based format that begins with a header line starting with a ">", followed by the sequence of nucleotides or
