Read the following statements and choose the correct option: 1. Adenine and Guanine are substituted pyrimidines 2. Uracil, cytosine and thymine are substituted purines 3. Adenine and Guanine are substituted pyrimidines while uracil, cytosine and thymine are substituted purines. 4. A nucleic acid containing deoxyribose sugar is called ribonucleic acid(RNA). 5. Uracil is a part of DNA

Step-by-step solution

Adenine and Guanine are substituted purines while uracil, cytosine and thymine are substituted pyrimidines ,"In the absence of any enzyme this reaction is very slow, with about 200 molecules of H2CO3 being formed in an hour. However, by using the enzyme present within the cytoplasm called carbonic anhydrase, the reaction speeds dramatically with about 600,000 molecules being formed every second."
