The nitrogenous bases in RNA are adenine, guanine, cytosine and uracil. Other than that, dideoxynucleotides are used in sequencing for the chain termination. There are several types of RNA. RNA is formed during transcription of genes in the genome by RNA polymerase. Nucleotides link together by phosphodiester bonds to form polynucleotide chains. This DNA is wrapped around histone proteins forming “beads on a string appearance”. So, next time you want to blame your baldness on your father and don’t know whether to berate your genes or your DNA, take a look at the differences below: DNA … Nucleic Acid: Nucleic acids are involved in gene expression as well as the storage of genetic information. “Nucleic acids (article).” Khan Academy. They are a nitrogenous base, a pentose sugar (five carbon sugar), and phosphate groups. For example, DNA contains two such chains spiraling round each other in the famous double helix shape. There are two main types of nucleic acids named DNA and RNA. Nucleotides also serve as an energy source. Nucleic Acid: Nucleic acid is the polymer of nucleotides. Ribonucleic acid (RNA) is a nucleic acid which is directly involved in protein synthesis. Nitrogenous bases form hydrogen bonds between complementary bases in the double stranded DNA. Nucleic Acid: Nucleic acid is composed of a chain of nucleotides, which are linked by phosphodiester bonds. When the pentose sugar is ribose, the forming nucleic acid is RNA. Side by Side Comparison – Nucleotide vs Nucleic Acid Now the structure is called chromatin (DNA + histone protein complex). Nucleotide: ATP, ADP, CMP, dGTP, ddATP are the examples of nucleotides. On the contrary, when the pentose sugar is deoxyribose, the resultant polynucleotide is called DNA. Nucleotides form phosphodiester bonds between 3’OH and 5’ Phosphate groups of adjacent two nucleotides to create the polynucleotide chain. Two types of nucleic acids can be found depending on the type of the pentose sugar in the nucleic acid backbone. Answers: 1, question: Which statements explain the primary difference between the structure of a nucleic acid and the structure of a protein? Furthermore, an amino acid has COOH, NH2 and R groups while a nucleotide has pentose sugar, a nitrogenous base and phosphate groups. Nevertheless, in DNA, uracil is replaced by thymine. However, in reality, they stand for very different things. Second and third letters refer to the number of phosphate groups and phosphate. On the other hand, when the pentose sugar is deoxyribose, the resultant nucleic acid is DNA. 2.Nucleotides are made up of nucleobase, carbon sugar, and phosphate while nucleic acids are made of polymer macromolecules which are nucleotides in nature. 1. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } Polymerization of nucleotides, which contain ribose as the sugar, forms RNA and the polymerization of nucleotides, which contain deoxyribose as the sugar, forms DNA. Therefore, this is the key difference between amino acid and nucleotide. Nucleic acids, mainly DNA, contain genetic information of the organisms. They are composed of phosphate groups, nitrogenous bases and pentose sugars. Describe the similarities and differences between the structure of ATP and a DNA nucleotide.
