A researcher is trying to construct a molecular-based phylogeny of the entire animal kingdom. Assuming that none of the followin
g genes are absolutely conserved, which of the following would be the best choice on which to base the phylogeny? A) genes involved in chitin synthesis
B) collagen genes
C) genes involved in directing segmentation development
D) genes involved in eye-lens synthesis
Collagen is found in bones,muscles,tendons and skin
It is the one which holds the body together
It strengthen and support many tissues in the body
Collagen genes encode many types of collagen which have a structural role in the extracellular matrix and has a great tensile strength
At least 26 different collagen polypeptide chains are present which are encoded by 26 unique collagen genes
Since collagen is the main protein of connective tissue in animals and is considered as the most abundant protein in mammals it can be the best choice to base the phylogeny
Rest all options are specific for a particular function in particular animals
