Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes. RNA and DNA are nucleic acids, and, along with lipids, proteins and carbohydrates, constitute the four major macromolecules essential for all known forms of life.


Ribonucleic acid (RNA) is typically single stranded and contains ribose as its pentose sugar and the pyrimidine uracil instead of thymine. An RNA strand can undergo significant intramolecular base pairing to take on a three-dimensional structure. There are three main types of RNA, all involved in protein synthesis.


Although there is only one strand of RNA, as opposed to the two stranded double helix of DNA, it does not always follow a linear pattern. Sometimes the molecules form loops and the nitrogenous bases bond. According to the website About, the structure of RNA is made up of three components, one of which is a five-carbon sugar called ribose sugar.


ADVERTISEMENTS: Read this article to learn about the composition and structure of DNA and RNA. Introduction: There are two types of nucleic acids, namely deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Primarily, nucleic acids serve as repositories and transmitters of genetic information. Brief History: DNA was discovered in 1869 by Johann Friedrich Miescher, a Swiss […]


Nucleic acid structure refers to the structure of nucleic acids such as DNA and RNA.Chemically speaking, DNA and RNA are very similar. Nucleic acid structure is often divided into four different levels: primary, secondary, tertiary and quaternary.


Structure. DNA and RNA are nucleic acids. Nucleic acids are long biological macromolecules that consist of smaller molecules called nucleotides.In DNA and RNA, these nucleotides contain four nucleobases — sometimes called nitrogenous bases or simply bases — two purine and pyrimidine bases each.


A large body of structural work conducted over the past ten years has elucidated mechanistic details related to 3' to 5' processing and decay of RNA substrates by the RNA exosome. This chapter will focus on the structural organization of eukaryotic exosomes and their evolutionary cousins in bacteria and archaea with an emphasis on mechanistic details related to substrate recognition and to...


DNA stands for deoxyribonucleic acid, while RNA is ribonucleic acid. Although DNA and RNA both carry genetic information, there are quite a few differences between them. This is a comparison of the differences between DNA versus RNA, including a quick summary and a detailed table of the differences.


The components of RNA are somewhat similar to DNA with three major differences. the pyrimidine base uracil replaces thymine and ribose sugar replaces deoxyribose. RNA mostly forms single stranded structure.
