Why are nucleic acids important? In this lesson, understand the nucleic acid structure and function in the body. Find a few examples of the...
Nucleotides contain what kind of sugars? What are the structures of RNA and DNA and how might one be used to create the other? What molecules make up single-stranded DNA? What biological macromolecule is made up of monomers? Nucleic acids are polymers of what monomers?
Define nucleic acids. A nucleic acid is a complex biomolecule that stores cellular information in the form of a code. Name the smaller subunits of nucleic acids. Nucleic acids are polymers made up of smaller subunits called nucleotides....
On the other hand, the more fragile RNA molecules play various biochemical roles, with one of the most significant being the direct instruction for protein synthesis [8]. The origin of nucleic acids on Earth remains a subject of debate. Nucleobases and ribose have been found in meteorites...
Aptamers are interesting molecules with properties of both antibodies and oligonucleotides. What make them more fascinating are their numerous applications in the fields of biotechnology and biomedicine. Further, the way in which the SELEX process has evolved over the years provides ample possibility for...
Proteins are organic molecules composed of Carbon, Hydrogen, Oxygen, and Nitrogen (CHON). Proteins are created by linking together amino acids into protein links called polypeptide chains. Amino acids consist of the following elements: carbon, hydrogen, oxygen, nitrogen, and, sometimes, sulfu...
is used to resolve molecules that tend to form secondary structures, such as RNA, TBE buffer is usually used; for example, polyacrylamide gels are primarily prepared with TBE buffer supplemented with 7–8 M urea or a similar denatur...
Carbon Molecules As an organic molecule, carbon acts as a key element of nucleic acids. Carbon atoms appear in the sugar of the nucleic acid backbone, and the nitrogenous bases. Oxygen Molecules Oxygen atoms appear in the nitrogenous bases, sugar, and phosphates of the nucleotides. An important...
32.7.2Peptide Nucleic Acids Peptidenucleic acids(PNAs) (Figure 32.5) are DNA analogs in which the sugar-phosphate backbone is replaced by N-(2-aminoethyl) glycine units[62,63]. These molecules efficiently hybridize with complementary DNA andRNA, forming double helices with Watson-Crickbasepairing[...
acids are abundant. (p)ppGpp and DskA bind to RNA polymerase directly which changes the transcription of many different genes to adapt to the lack of amino acids by slowing growth. C) Cyclic-di-GMP (c-di-GMP) is created from two GTP molecules by enzymes that contain a protein domain ...
