what similarities would be found in the dna structure of genes from a cat human and eucalyptus tree
The amounts of adenine and thymine in the DNA of a human, cat, and  eucalyptus tree are all very similar. Also the adenine and guanine  amounts will always equal the thymine â¦ and cytosine amounts.og (canine) DNA has fewer genes than both human and mou â¦ se DNA and have fewer similarities. The homology of humans to mice genes is approximately 99% while the homology of humans to dog genes is around 94%.
