What is the structure difference of dna and rna

A major difference between DNA and RNA structure is in their monomers. They are a pentose sugar, phosphate group and a nitrogenous base. Summary of Differences Between DNA and RNA.
Also, both their nucleotides have a similar structure with slight differences. An Overview of the Types of RNA. RNA has a simpler structure and is needed in order for DNA to function. Accordingly, the deoxyribonucleotide is the building block of DNA while the ribonucleotide is the building block of RNA. The most likely answer for this is that having a double-stranded molecule helps protect the genetic code from damage. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose.
Moreover, the nucleotides of each nucleic acid have two different purine bases and pyrimidine bases. An Introduction to DNA Transcription. Both are polymers made from nucleotides. DNA and RNA are two types of nucleic acids present in living organisms. Also, RNA is found in prokaryotes, which are believed to precede eukaryotes.
