Splign is a powerful computer tool made by the National Center for Biotechnology Information (NCBI Splign). It helps scientists match a processed genetic sequence (cDNA) back to its original home on a large chromosome (Genomic Map).
This process is called spliced alignment. It works like a puzzle solver. It takes a gene that has had its extra pieces cut out and figures out exactly where those pieces used to sit on the full DNA strand. 🧬 Why Use Splign?
When a cell reads DNA to make a protein, it copies the gene into RNA. Then, it cuts out the junk parts (introns) and glues the good parts (exons) together. Scientists copy this edited RNA back into stable DNA, which is called cDNA.
Splign helps you compare that cDNA to the big genome to find: Exact positions of exons and introns. Hidden gene copies (duplications). Small mistakes or changes in the sequence (mismatches). 🛠️ How to Run Your First Alignment
You can use Splign online through a web browser or by using NCBI’s free Genome Workbench software. Here are the basic steps to run your first alignment: 1. Gather Your Data
You need two pieces of information, usually in a text format called FASTA:
