Nitrogen in Biology

DNA = Genetic information carrier RNA = Protein synthesis intermediate Proteins = Building blocks of enzymes All of the above = Essential components of life

Nitrogen is essential for life = True Nitrogen is a rare gas in the atmosphere = False Most organisms can use atmospheric nitrogen = False Nitrogen is only found in proteins = False

Building blocks of life = Essential components of life The majority of the air we breathe = Nitrogen in the atmosphere Unable to use nitrogen as it exists = Inability to utilize atmospheric nitrogen Essential component of DNA, RNA, and proteins = Nitrogen's biological role
