DNA and RNA are somewhat similar organic molecules, both involved in the storage and transfer of genetic information. According to About.com, DNA’s primary function is to store genetic information over the long term, while RNA’s primary function is to transfer this information to the ribosomes, where proteins are made. Because they perform different functions, they have different structures, chemistry and characteristics.Know More
About.com states that DNA stands for deoxyribonucleic acid, while RNA stands for ribonucleic acid. The difference in their names indicates the primary chemical difference between them, with RNA possessing the sugar ribose and DNA possessing deoxyribose. Ribose contains one more –OH group of atoms in each molecule than deoxyribose does, but it is missing a -H ion that is present in deoxyribose. DNA is susceptible to being damaged by ultraviolet rays, whereas RNA is somewhat resistant to damage from these rays. RNA molecules are susceptible to pH imbalances and do not remain stable when exposed to alkaline conditions, whereas DNA molecules remain stable under such conditions.
Structurally, the two look very different. As explained by About.com, RNA molecules are helically shaped, whereas DNA molecules take the form of a double helix. DNA molecules are able to produce RNA molecules by virtue of this double-sided design.Learn more about Molecular Biology & DNA
DNA polymerase II is a type of DNA polymerase: a category of enzymes that synthesize identical copies of existing DNA, allowing dividing cells to pass this genetic information on to their daughter cells. DNA polymerase II is found only in prokaryotes, or unicellular organisms, such as archaea, and simple bacteria that lack membrane-bound nuclei and organelles.Full Answer >
DNA replication is a process in which DNA is duplicated so that it can be integrated into a new cell during cell division. The process produces two identical replicas of the DNA molecule from one original DNA molecule. It occurs in every living organism on Earth, allowing parental generations to pass on genes to their offspring.Full Answer >

DNA, or deoxyribonucleic acid, is genetic material that exists in nearly all living organisms, including humans. Any organism with nucleus-based cells has DNA. It is the building blocks forming an organism, and the DNA combination an organism is born with remains the same.Full Answer >
