Nucleic acids are the biopolymers , or small biomolecules , essential to all known forms of life. 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 ; if the sugar is derived from ribose as deoxyribose , the polymer is DNA deoxyribonucleic acid. Nucleic acids are the most important of all biomolecules. These are found in abundance in all living things, where they function to create and encode and then store information of every living cell of every life-form organism on Earth. In turn, they function to transmit and express that information inside and outside the cell nucleus—to the interior operations of the cell and ultimately to the next generation of each living organism. The encoded information is contained and conveyed via the nucleic acid sequence , which provides the 'ladder-step' ordering of nucleotides within the molecules of RNA and DNA.

  1. The sugar-phosphate backbone of each chain is on the outside in all structures one red and one blue with the bases silver oriented inward. Gain- and loss-of-function studies, in silico predictions and sensor assays in vivo demonstrate that miR-9 targets several components of the Fgf signaling pathway, Harry M. Pxf are attractive targets for mol. Choi.

  2. Nucleic acids are molecules that allow organisms to transfer genetic information from one generation to the next. These macromolecules store the genetic information that determines traits and makes protein synthesis possible. Two examples of nucleic acids include deoxyribonucleic acid better known as DNA and ribonucleic acid better known as RNA. These molecules are composed of long strands of nucleotides held together by covalent bonds. Nucleic acids can be found within the nucleus and cytoplasm of our cells. 💩

Stem-cell based gene delivery mediated by cationic niosomes for bone regeneration purposes. Figure 9: Dual-labeled PNA beacons with end-stacking or intercalating quencher. These large DNA units in association with proteins can be stained with dyes and visualized in the light microscope as chromosomes.

  4. Group Leader: Ramon Eritja. The synthesis of nucleic acids DNA and RNA is in constant evolution providing a wide range of versatile tools with applications in therapeutics, and material science. Our studies are aimed at gaining a better understanding of novel nucleic acids by chemical modification with the objective of evaluating their efficacy in antisense and RNA interference therapies. 👺
