Name two biologically important compounds that contain both oxygen and nitrogen

Two biologically important compounds that contain both oxygen and nitrogen: i) Nucleic acids (DNA and RNA) Nucleic acids are biopolymers, or small biomolecules, essential to all known forms of life. They are composed of monomers, which are nucleotides made of three components: a 5-carbon sugar, a phosphate group, and a nitrogenous base. ii) Proteins Proteins are made up of smaller building blocks called amino acids, joined together in chains.Amino acids are organic compounds containing amine (-NH 2) and carboxyl (-COOH) functional groups, along with a side chain (R group) specific to each amino acid. ​​​​​​​ Q. Which of the following can convert the nitrogen molecules present in air into nitrates and nitrites? (a) a biological process of nitrogen-fixing bacteria present in the soil (b) a biological process of carbon fixing factor present in the soil (c) any of the industries manufacturing nitrogenous compounds Q. Question 9 The nitrogen molecules present in air can be converted into nitrates and nitrites by (a) a biological process of nitrogen fixing bacteria present in soil (b) a biological process of carbon fixing factor present in soil (c) any of the industries manufacturing nitrogenous compounds (d) the plants used as cereal crops in field
