What is water's role in the nucleic acid? Water keeps the nucleic acids lubricated so they can perform their function more efficiently. Water keeps the nucleic acid hydrated. In plant and animal cells, most of the nucleic acids are found in the nucleus of cells, surrounded by water and charged metal ions.
Answer (1)
Water plays several critical roles in the functioning of nucleic acids, such as DNA and RNA:
Hydration : Water molecules help maintain the structure and stability of nucleic acids by keeping them hydrated. This hydration is essential because the stability of the double helix in DNA and the three-dimensional structures of RNA depend on the presence of water molecules.
Interaction with Ions : In cells, nucleic acids are often surrounded by water and charged metal ions, such as magnesium ions (Mg²⁺). Water helps to create an environment where these ions can interact with the nucleic acids, which is crucial for maintaining their proper shape and function.
Participation in Reactions : Water is also involved in biochemical reactions that nucleic acids undergo, such as hydrolysis and phosphorylation. During these reactions, water may act as a reactant or participate indirectly by stabilizing the transition states of molecules.
In summary, water is indispensable for nucleic acids because it helps maintain their structure, enhances stability through interaction with ions, and participates in important biochemical reactions.
