Quiz 9 Key 745 lab 1 Define DNAdependent RNApolymerase Polymerase enzymes that are DNAdep endent use DNA as the template or pattern for building new nucleic acid molecules An RNApolymerase builds RNA ie it uses nucleotides containing the sugar ribose and some containing the base uracil but not thymine RNApolymerase is involved in both replication and transcription in prokaryotic cells and the core enzymes are pretty much the same each has four subunits designated as own 5 and 5 the sigma factors differ Translation Translation involves reproducing information provided in one language in a different language In biology it refers to the process of protein synthesis because the information stored in mRNA nucleotide sequences one language is used to determine the amino acid sequences ofpolypeptide chains second language The process occurs at ribosomes Genome The term genome usually refers to the total DNA content within the chromosome s of an organism In some viruses it may refer to the total RNA content because RNA is the only nucleic acid present Plasmid DNA mitochondrial DNA and chloroplast DNA is usually not considered as part of the genome 2 Transcription 3 MessengerRNA mRNA introns polycistronic 4 AminoacyltRNAsynthase anticodon 5 These small RNA molecules play an essential role in the regulation of gene expression They are the focus ofintensive research 6 Peptidyl transferase 7 Sigma factor promoter operator 8 Tryptophan 9 Permease allolactose 10 Catabolite repression cyclicAMP 11 Genetics The etiological agents of Gastric ulcers are Helicobacter pylori
