This is useful for a molecule that has to be produced, degraded, and recycled constantlyĭVA vs RNA What is the difference between DNA vs RNA? Therefore, it is especially not stable under alkaline conditions and is susceptible to enzyme attack. This stability is useful for a molecule in charge of keeping genetic material intactĭue to its extra oxygen (in the hydroxyl group), RNA is more reactive than DNA. RNA forms in the nucleolus and is found in the cell’s cytoplasmĭNA is highly stable, thanks to its strong C-H bonds and the fact that it contains one less hydroxyl group. RNA molecules vary in length, but they are much shorter than DNAĭNA is located in the nucleus, with some DNA found in the mitochondria A single strand of DNA would be around 2 m long In comparison, DNA is much longer than RNA. Ribose sugar is a monosaccharide containing four hydroxyl groups RNA is a single stranded molecule but intermittently forms a double helix structureĮach nucleotide contains a phosphate group, a 5-carbon sugar, and a nitrogenous base (adenine, guanine, cytosine, thymine)Įach nucleotide contains a phosphate group, a 5-carbon sugar, and a nitrogenous base (adenine, guanine, cytosine, uracil)ĭeoxyribose sugar is a monosaccharide containing three hydroxyl groups (-OH –) Store and replicate genetic information-the blueprint for all genetic traitsĪ copy of DNA with instructions on cellular functions and protein synthesis CC- Attribution-Share Alike 3.0 Unported. Physical differences between DNA and RNA. Let’s go over these differences and similarities and discover why they are pivotal to life. DNA and RNA are both nucleic acids and carry genetic information, but they also have their differences. DNA stands for deoxyribonucleic acid, and RNA stands for ribonucleic acid. What is the difference between DNA vs RNA? These molecules are the most important building blocks in living things as they help make life possible. Similarities Between DNA vs RNA Molecules.

What is the difference between DNA vs RNA?.

Before cell division, these chromosomes are duplicated (by DNA replication) and provide a complete set of chromosomes for each daughter cell, whereas a circular coiled DNA is located in the cytoplasm of a prokaryotic cell. The eukaryotic DNA is organized into genetic structures called chromosomes.

They postulated the Watson and crick model of the DNA double helix which is accepted worldwide. Note:- DNA was first isolated by Friedrich Miescher and its molecular structure was identified by Francis Crick and James Watson. The backbone of DNA is the portion which provides structural support to the two strands and is made up of alternating sugar and phosphate groups while nitrogenous bases face inside. According to the base pairing rule to make double-stranded DNA, adenine forms a base pair with thymine and cytosine forms a base pair with guanine. Hydrogen bonds are formed between the nitrogen bases. Two successive nucleotides are joined by covalent bonds called phosphodiester bonds present between the sugar of one nucleotide and phosphate of the alternating sugar phosphate. Each nucleotide is composed of one of the four nitrogen molecules containing nucleobases (cytosine, guanine, adenine or thymine), a deoxyribose sugar and a phosphate group. The two strands of DNA chain run in opposite directions to each other and are thus called antiparallel.Ĭomplete Answer:-DNA is a heteropolymer of deoxyribonucleotides, which are made up of a pentose sugar, nitrogenous bases and a phosphate moiety. Hint:-Deoxyribonucleic acid is a double helix structure composed of two polynucleotide chains that coil around each other to form a genetic molecule carrying genetic instructions for the growth, development and reproduction of organisms.
