0 ASCP Molecular Biology Exam Prep 1 1. Pyrimidine: one carbon ring Cytosine, Thymine, Uracil 2. Purine: two carbon rings Adenine, Guanine 3. How are nucleotides joined together?: condensation 4. What does mRNA do?: carries code out of cell. code for protein structure. DNA to ribosomes end of transcription start of translation 5. What does tRNA do?: decodes mRNA. Matches amino acids to mRNA code. Protein synthesis 6. What does rRNA do?: part of ribosome structure most abundant RNA coordinated coupling of tRNA to mRNA codons 7. Feedback Inhibition: end product of pathway is noncompetitive inhibitor binds to allosteric site to slow down rxn b/c too much product 8. Exonucleases: degrades nucleic acids by removing one terminal nucleotide at a time cleaves phosphodiester bond at end of chain 5' ---> 3' and 3' ---> 5' 9. Endonucleases: cleaves phoshpodiester bonds w/in chain recognition site is palindromic sequence cleaves unevenly, leaves sticky ends (restriction enzymes) 10. DNA polymerase III: copies DNA by reading existing strand, builds new comp. strand always adds to 3' end can't start new strand on its own (ORI sites) 11. ORI sites: origin of replication on chromosome triggers DNA replication 12. gyrase: unwinds DNA in front of fork 13. DNA polymerase I: removes RNA nucleotides form RNA primers and replaces with DNA (makes sure primers that start replication are removed) 14. helicase: breaks H-bonds of double helix
