Compare the amounts of adenine, guanine, cytosine and thymine found in the DNA of each of the cells studied which are: Human liver, Human thymus, Herring sperm and Yeast. In Human liver adenine is 30.3, guanine is 19.5, cytosine is 19.9 and thymine is 30.3. In Human thymus, adenine is 30.9, guanine is 19.9, cytosine is 19.8, and thymine is 29.4. In Herring sperm, adenine is 27.8, guanine is 22.2, cytosine is 22.6, and thymine is 27.5. In Yeast, adenine is 31.7, guanine is 18.2, cytosine is 17.4, thymine is 32.6. What fact can you state about the overall composition of DNA, regardless of its source?
