What Is The Structural Difference Between Dna And Rna

Dna consists of two strands arranged in a double helix.

Dna is found in the nucleus plastids and mitochondria of the cell. Dna has a double standard helix like structure whereas rna has a simple standard structure. On the other hand rna is found in the nucleus cytoplasm and ribosomes. Rna only has one strand but like dna is made up of nucleotides.

It is a coupler between protein building block and genetic code. Structural differences between dna and rna. Deoxyribonucleic acid is made up of deoxyribose sugar while ribonucleic acid is made up of ribose sugar. It has two nucleotide strands which consist of its phosphate group five carbon sugar the stable 2 deoxyribose and four nitrogen containing nucleobases.

Adenine thymine cytosine and guanine. Nucleic acids are macromolecules or biopolymers. The significance of rna it is the dna s photocopy. Dna is a double stranded molecule while rna is a single stranded molecule.

One of the primary differences between dna and rna is that dna is double stranded while rna is single stranded. Dna contains the sugar deoxyribose while rna contains the sugar ribose. It is a structural component of ribosomes. The only difference between ribose and deoxyribose is that ribose has one more oh group than deoxyribose which has h attached to the second 2 carbon in the ring.

Moreover they are the building blocks of genetic material of an organism. Dna is found in the nucleus of a cell nuclear dna and in mitochondria mitochondrial dna. Each nucleotide contains a phosphate a 5 carbon sugar molecule and a nitrogenous base.
