To describe:
The general structure of DNA and RNA molecules.
Concept introduction:
DNA and RNA are two types of
DNA generally stores genetic information while the RNA acts as a helper molecule that carries information from DNA for the synthesis of proteins.
Pictorial representation: The general structure of DNA and RNA are as follows:
Fig.1: The structure of DNA and RNA.
Explanation of Solution
The DNA is a
In DNA molecule, the nucleotides are linked to each other by a phosphodiester linkage. The DNA molecules are usually double stranded with a complementary base pairing between the two strands.
On the other hand, the RNA is also a polymer of nucleotides, but it contains nitrogenous base Uracil instead of Thymine. It is usually single-stranded and contains ribose sugar unlike deoxyribose sugar in DNA.
The DNA is a double-stranded genetic material that differs structurally from RNA which is a single-stranded molecule.
