Small nuclear rna snrna - Study guides, Class notes & Summaries

Nucleic Acid - correct answer A polymer (long repeating chain) of nucleotides - covalently bonded together. Deoxyribonucleic Acid (DNA) - correct answer Usually a double helix made up of 2 chains of deoxyribonucleotides. Ribonucleic Acid (RNA) - correct answer Usually a singe-stranded chain of ribonucleotides. Nucleotides - correct answer These are the building blocks of nucleic acids. The contain a central sugar ring (containing an oxygen and several carbons), 1 to ...

BIO 120 3rd Exam: Intracellular Protein Sorting and Maintenance of Cell Compartmentalization Compartmentalization - Due to network inside the cell Eukaryotic Cell Compartment Assembly of organelle depends on protein transported to it Highly regulated, specific and targeted Intracellular Compartment Nucleus continuous in cytosol (topologically continuous) o Molecules can move from one place to another without crossing the membrance Secretory and endocytic network o Vesicles, endoso...

Study guide test 2 Strategies of nucleotide synthesis: precursors, when is ribose added, how is ribose activated and added, what are first purines and pyrimidines made, how are the various forms of THF made and/or interconverted, regulation of purine synthesis (where are committed steps), how is a balance between AMP and GMP achieved, how do folic acid antagonists impair purine synthesis. • Pyrimidines: base is made before adding the ribose sugar • Purines: ribose is already present  suga...
