Multiple genes comparison

Question

[cdjeu]

Dear all, I would like to compare multiple genes to find their similarities or dissimilarities in term of amino acids composition and localization, exons and intros positions. Could you recommend me tools and programs? Thanks!

This looks like a very basic question and this is totally fine if you're beginning, so, rather than just give you some random software and expecting you get awesome results outta nowhere, I'd suggest you should maybe read some theoretical background, from NCBI Books or Biostars Handbook for example.
