I want check the similarity of a list of genes' 5′-UTR regions across different species. Anybody could recommend me to do it in an efficient way, please?
There is a list of sotwares able to align sequences and analyze molecular diversity (even freely available softwares). Most of them depend on FASTA format. It is important to get the same sizes (the same number of nts) before starting the procedure. A fast way to obtain the sequences in different species is starting by a BLASTn analysis from a reference sequence in a particular species. You'll get the accession numbers of the aligned sequences in as many species as you want. You may even define the species of your interest in the first page of BLASTn
