True: Nitrogen Atoms in Purine Rings Come from Glutamine

Purine rings are an essential part of DNA and RNA, which are both involved in the storage and transfer of genetic information. The nitrogen atoms in purine rings come from an amino acid called glutamine. Glutamine is a non-essential amino acid and is an important source of nitrogen for DNA and RNA synthesis. This is because glutamine is the only amino acid that contains two nitrogen atoms in its side chain (Clinical Biochemistry, 2016). The process by which glutamine is transformed into purine rings is known as transamination. This occurs when an aminotransferase enzyme binds to glutamine and transfers its two nitrogen atoms to the carbon skeleton of an organic acid, forming a new amino acid and a new organic acid (Mater et al. 2018). The newly formed amino acid is then converted into a purine base and incorporated into DNA or RNA. In summary, it is true that nitrogen atoms in purine rings come from glutamine. Glutamine is an essential amino acid that is metabolized by an enzyme to form purine bases, which are then incorporated into DNA and RNA. This process is essential for the storage and transfer of genetic information (Khare et al. 2021). Cont….
