What is DNA? Correct Answer-A linear, double-stranded structure composed of multiple units of four different nitrogenous bases, each attached to a sugar molecule Bases are nucleoprotiens created from proteins we eat. They can be single ring structures (pyrimidines) or double-ring structures (purines). What are the pyrimidines and what are purines? Correct Answer-Adenine and Guanine are purines. Thymine and cytosine are pyrimidines What is the purpose of a gene? Correct Answer-To code for t...
