Why is the groin swollen when our toe is injured

Because when your toe is injured it sends a pulse to your groin that causes your groin to fell pain so your brains neuropathegens dont feel as much pain transmiting through your toe. Hope this helps :)

explanation:

the sequence of amino acids in a protein determines its function. the dna sequence of a gene determines the amino acid sequence of the resulting protein. thus, any changes in dna sequence can result in changes in protein function. this is called a mutation.
