Transcript alignment and selection Genome wide study 2024 Part 05

When we get the protein family sequences after blast, some genes have more than one transcript and we have to select one of them. How to select the transcript? What is a transcript of the gene? Why gene have multiple transcripts? How to do protein family analysis? How to do genome wide analysis? How to do gene alignment? How to do multiple sequence alignment? What is protein sequence alignment? How to do protein alignment? Protein protein alignment How to select mutation? How to use Genome Jp database?
