So I am preparing some documents about Sar-Cov2 and I wanted to illustrate the "definition" of the virus with the DNA sequence. I found this sequence in GenBank.
Now I think I need an explanation about what this sequence described exatly. From y research, I understood:
- The first part of the text listed genes that had been identified in Sar-Cov2. Each gene would be responsible of a "feature" of the Sars-Cov2.
- The second part, named "Origin" in the text, is the complete DNA sequence of the virus.
Now my question is: how is one gene from the first linked to the second part? Is there some sort of "stamp" that allows to say: "gene X starts at fifth letter in DNA sequence and ends at tenth"? If yes, is the information in the text from GenBank (link above)?
Example of the pieces of the file:
