nucleic acid function

All nucleic acids contain the bases A, C, and G; T, however, is found only in DNA, while U is found in RNA. Nucleic acids are naturally occurring chemical compounds that serve as the primary information-carrying molecules in cells. Nucleic Acid functions and examples Storage and transmission of genetic code (DNA/RNA) Processing genetic info (ribozymes) Protein synthesis (tRNA and rRNA) They play an especially important role in directing protein synthesis. This … This DNA helps to replicate the features from one generation to another. Nucleic acid, naturally occurring chemical compound that is capable of being broken down to yield phosphoric acid, sugars, and a mixture of organic bases (purines and pyrimidines). They act as nuclear receptors and few drugs and hormones act on these receptors and bring about the necessary changes in the cells and in the body. The inset shows the corresponding pentose sugar and pyrimidine base in ribonucleic acid (RNA). Nucleic acids are the molecules that carry the genetic information that is passed down from parent to child. These are called ribozymes. They are composed of nucleotides, which are the monomers made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base.If the sugar is a compound ribose, the polymer is RNA (ribonucleic acid… Our editors will review what you’ve submitted and determine whether to revise the article. In deoxyribonucleic acid, DNA, hydrogen bonds form between specific bases of two nucleic acid chains, forming a twisted, double-stranded DNA molecule that looks like a spiral staircase, with the two sugar-phosphate … Furthermore, nucleic acids contain specific segments called genes that are responsible for producing every protein in your body. During cell division, each DNA moves up to each living daughter cell. This leads to the formation of a pair of DNA in the cell prior to mitosis. The functions of nucleic acids have to do with the storage and expression of genetic information. A. regulate cell processes B. provide structure C. transmit genetic information D. fight disease. You might have already known the involvement of nucleic acids in cell division, mRNA formation, and protein synthesisfrom your biochemistry subject. Expression of your genes controls the biological characteristics … Though the person does not have the memory of his forefathers, the DNA has it and hence he attains their physical features. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. Nucleic acids are long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. The specific order of nucleotides in the molecule of DNA or RNA is what determines the genetic information it carries. All nucleotides are made of three subunits: one or more phosphate … Nucleic Acid Functions Basic Characteristics of Nucleic Acids. Purine is salvaged in the form of the corresponding nucleotide, whereas pyrimidine is salvaged as the nucleoside. Recipient of 1993 Nobel Prize for Physiology or Medicine. DNA is the genetic material found in all living organisms and is found in the … Only two nucleic acids are believed to … New copies of DNA are created by the process of DNA replication. They are used as building blocks of the body and they help in shaping the tissues and organs of the body. This article covers the chemistry of nucleic acids, describing the structures and properties that allow them to serve as the transmitters of genetic information. Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group. 5 C. 10 D. 20. For a discussion of the genetic code, see heredity, and for a discussion of the role played by nucleic acids in protein synthesis, see metabolism. RNA is the genetic material of certain viruses, but it is also found in all living cells, where it plays an important role in certain processes such as the making of proteins. The two rings in purines are synthesized while attached to the ribose phosphate during the assembly of adenine or guanine nucleosides. form of protein molecules (20). The six-atom pyrimidine ring is synthesized first and subsequently attached to the ribose phosphate. They are present in all the living cells. Thus it also helps to preserve genetic information. In both cases the end product is a nucleotide carrying a phosphate attached to the 5′ carbon on the sugar. The purpose of DNA is to act as a code or recipe for making proteins. Nucleic acids are responsible for the storage, transmission, and expression of genetic information in organisms. Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing.
