Cyanobacteria Produce N-(2-Aminoethyl)Glycine, a Backbone for Peptide Nucleic Acids Which May Have Been the First Genetic Molecules for Life on Earth
Prior to the evolution of DNA-based organisms on earth over 3.5 billion years ago it is hypothesized that RNA was the primary genetic molecule. Before RNA-based organisms arose, peptide nucleic acids may have been used to transmit genetic information by the earliest forms of life on earth. We discovered that cyanobacteria produce N-(2-aminoethyl)glycine (AEG), a backbone for peptide nucleic aci...
متن کاملSingle-molecule manipulation of nucleic acids.
During the past decade, local force measurement techniques, such as atomic force microscopy and optical tweezers, were used to study the elastic properties and mechanically induced structural transitions of nucleic acids at the single-molecule level. Single-molecule manipulation has also increasingly been used to investigate DNA-dependent enzymatic processes, with implications for unfolding and...
متن کاملMay-Thurner Syndrome With Pulmonary Embolism as the First Presentation Rather Than Deep Vein Thrombosis.
May-Thurner syndrome (MTS) is a rare disease that causes deep vein thrombosis (DVT) in young females (age 20 to 50). DVT is caused by mechanical obstruction of the left common iliac vein by the right common iliac artery resulting in stasis rather than a primary hypercoagulable state. Although MTS is found in 22% of cadavers, it causes <5% of lower extremity venous disorder. Greater than 70% com...
متن کاملI-36: Preimplantation Genetic Diagnosis - Where Have We Been and Where Are We Going
Preimplantation genetic diagnosis (PGD) is now considered routine in IVF laboratories with micromanipulation capability and access to genetic diagnostic services. The past two decades have witnessed a dramatic increase in the use of PGD, the number of cycles performed, and the indications for which PGD has been used. This increase has been mirrored by a slow, but steady, increase in the range o...
متن کاملCellular Morphology and Immunologic Properties of Escherichia coli Treated With Antimicrobial Antisense Peptide Nucleic Acid
Background & Objectives: Antisense peptide nucleic acids (PNA) that target growth essential genes show potent bactericidal properties without cell lysis. We considered the possibility that whether PNA treatment influence the bacteria total nucleic acids content and apply approach to develop a new delivery system to Dendritic cells (DCs). DCs are the most potent antigen presenting cells in th...
