  • how to do a phylogenetic tree

    Dear All, as I'm new to the topic and on this forum you may apologize my trivial questions. I have one: from a sequence alignment of DNA sequences, is there a way to obtain a tree based on a codon position ? I would like to compare it to the standard phylogenetic tree. Many thanks for your kind help !

    Hi,
    maybe you ehave to be a bit more precise. What do you mean with "based on a codon position"? Do you have an alignment of protein-coding sequences and want to exclude two two positions (1st and 3rd for example)?

      Recent Developments in Metagenomics
      by seqadmin





      Metagenomics has improved the way researchers study microorganisms across diverse environments. Historically, studying microorganisms relied on culturing them in the lab, a method that limits the investigation of many species since most are unculturable1. Metagenomics overcomes these issues by allowing the study of microorganisms regardless of their ability to be cultured or the environments they inhabit. Over time, the field has evolved, especially with the advent...

      Understanding Genetic Influence on Infectious Disease
      by seqadmin




      During the COVID-19 pandemic, scientists observed that while some individuals experienced severe illness when infected with SARS-CoV-2, others were barely affected. These disparities left researchers and clinicians wondering what causes the wide variations in response to viral infections and what role genetics plays.

      Jean-Laurent Casanova, M.D., Ph.D., Professor at Rockefeller University, is a leading expert in this crossover between genetics and infectious...
