Dna vs rna

DNA is stable in alkaline conditions.

Dna vs rna

DNA is completely protected by the body i. Each carbon binds to a hydrogen atom and a hydroxyl group, which is a molecule of one oxygen and one hydrogen atom.

structural and functional difference between dna and rna

Points of comparison. This genetic material codes for the production of proteins and is passed down from parent organisms to offspring.

RNA is more resistant to damage by ultra-violet rays. Nucleic Acids Research. DNA can be damaged by exposure to ultra-violet rays. If one strand is broken, the other strand can serve as a template for repair. Its primary function is to directly codes for amino acid and serves as a messenger between the DNA and ribosomes to create proteins. Its nucleotides include uracil, A, G, and C. This genetic material codes for the production of proteins and is passed down from parent organisms to offspring. It can be found inside the nucleus, free-floating in the cytoplasm as well as within organelles like the endoplasmic reticulum. Deoxyribose is identical to RNA's ribose except that one carbon binds to a hydrogen atom instead of a hydroxyl group. Each carbon binds to a hydrogen atom and a hydroxyl group, which is a molecule of one oxygen and one hydrogen atom. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil. This picture shows how the two strands of DNA bond with each other and the bonds within the strand itself! Its primary role is to store and transfer genetic information. Another difference between the two molecules is their location in the cell.

If one strand is broken, the other strand can serve as a template for repair. Structure of ribose in RNA Structure of deoxyribose in DNA Functions[ edit ] DNA is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms.

It has a double-helix structure in eukaryotic cells.

Dna and rna similarities

DNA is completely protected by the body i. It is single-stranded and available in various shapes and types. RNA, ribose sugar is more reactive because of the presence of hydroxyl group on C 2. Its molecule can easily fold back on itself because of its single-stranded structure. However, no primer is needed for RNA. Points of comparison. In DNA, the bases of each strand bind to the bases on the other strand, forming the double-helix structure. Its primary function is to directly codes for amino acid and serves as a messenger between the DNA and ribosomes to create proteins. DNA plays no role in translation. DNA is used to carry an organism's genetic information while RNA takes on many different roles, for instance, RNA can act as an enzyme such as ribozyme. RNA has a simple structure. RNA is unstable in alkaline conditions. A deoxyribonucleotide consists of a phosphate group, five carbon deoxyribose sugar, and one of DNA's four nitrogenous bases: thymine, cytosine, guanine or adenine. It has smaller grooves where the damaging enzyme can attach which makes it harder for the enzyme to attack DNA; RNA, on the other hand, has larger grooves which makes it easier to be attacked by enzymes. Both consist of molecular chains containing alternating units of sugar and phosphate.
