    9165   Nucleotide Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Nucleotides Any Nucleoside That Is Esterified with (ortho)phosphate or an Oligophosphate At Any Hydroxyl Group On the Glycose Moiety; May Be Mono Di or Triphosphate; This Definition Includes Cyclic Nucleotides (nucleoside Cyclic Phosphates). 
    32259   Methylation  The Process in Which a Methyl Group Is Covalently Attached to a Molecule. 
    5634   Nucleus  A Membrane Bounded Organelle of Eukaryotic Cells in Which Chromosomes Are Housed and Replicated. in Most Cells the Nucleus Contains All of the Cell's Chromosomes Except the Organellar Chromosomes and Is the Site of RNA Synthesis and Processing. in Some Species or in Specialized Cell Types RNA Metabolism or DNA Replication May Be Absent. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    5739   Mitochondrion  A Semiautonomous Self Replicating Organelle That Occurs in Varying Numbers Shapes and Sizes in the Cytoplasm of Virtually All Eukaryotic Cells. It Is Notably the Site of Tissue Respiration. 
    5743   Mitochondrial Inner Membrane  The Inner I.e. Lumen Facing Lipid Bilayer of the Mitochondrial Envelope. It Is Highly Folded to Form Cristae. 
    5759   Mitochondrial Matrix  The Gel Like Material with Considerable Fine Structure That Lies in the Matrix Space or Lumen of a Mitochondrion. It Contains the Enzymes of the Tricarboxylic Acid Cycle and in Some Organisms the Enzymes Concerned with Fatty Acid Oxidation. 
    16020   Membrane  Double Layer of Lipid Molecules That Encloses All Cells and in Eukaryotes Many Organelles; May Be a Single or Double Lipid Bilayer; Also Includes Associated Proteins. 
    8168   Methyltransferase Activity  Catalysis of the Transfer of a Methyl Group to an Acceptor Molecule. 
    16740   Transferase Activity  Catalysis of the Transfer of a Group E.g. a Methyl Group Glycosyl Group Acyl Group Phosphorus Containing or Other Groups From One Compound (generally Regarded As the Donor) to Another Compound (generally Regarded As the Acceptor). Transferase Is the Systematic Name For Any Enzyme of EC Class 2.
