BISC 101 LAB EXAM QUESTIONS WITH
COMPLETE SOLUTIONS GRADED A+.


1. Promotor - ANSWER A region of DNA with a specific
sequence that tells RNA polymerase where to begin
transcription. Aka binding site for RNA


2. Terminator - ANSWER A special sequence of nucleotides
in DNA that marks the end of a gene. It signals RNA
polymerase to release the newly made RNA molecule,
which then departs from the gene. This forms a hairpin
loop


3. Intron - ANSWER sequence of DNA that is not involved in
coding for a protein


4. Exon - ANSWER expressed sequence of DNA; codes for a
protein


5. Template - ANSWER Used to be synthesized


6. Coding - ANSWER Creates mRNA from the code

,7. In bacteria there is _______ mRNA polymerase -
ANSWER One


8. Promotor region (eukariotic) - ANSWER TATA box


9. Start codon - ANSWER AUG


10. Promotor region (bactiria) - ANSWER -35 to -10 site


11. Isoform - ANSWER Splice DNA to get different genes


12. Activation energy - ANSWER Energy needed to get a
reaction started




13. Primary structure bonds - ANSWER Peptide
bonds/covalent bonds

, 14. secondary structure bonds - ANSWER hydrogen
bonds


15. Tertiary structure bonds - ANSWER Bonds with other
secondary structures, non covalent bonds,Ionic or
electrostatic,H-bonds,Van Der Waals,Disulfide bonds


16. Quaternary structure bonds - ANSWER Bonds with
other tertiary structures,secondary,primary and Disulfide
bonds


17. Sequence determines - ANSWER The structure


18. ATP - ANSWER Negatively charged


19. Enzymes stabilize... - ANSWER the transition state so
