Define phosphodiester bond.
Understand the Problem
The question is asking for a definition of a phosphodiester bond, which is a key concept in the structure of nucleic acids like DNA and RNA.
Answer
A covalent bond connecting a phosphate group and two sugar molecules in DNA and RNA.
A phosphodiester bond is a covalent bond that connects a phosphate group and two sugar molecules in the backbone of DNA and RNA, linking the 3' carbon of one nucleotide's sugar to the 5' carbon of the adjacent nucleotide's sugar.
Answer for screen readers
A phosphodiester bond is a covalent bond that connects a phosphate group and two sugar molecules in the backbone of DNA and RNA, linking the 3' carbon of one nucleotide's sugar to the 5' carbon of the adjacent nucleotide's sugar.
More Information
Phosphodiester bonds are crucial for the stability of DNA and RNA, forming the backbone of these macromolecules.
Tips
A common mistake is confusing phosphodiester bonds with peptide bonds, which link amino acids in proteins.
