PCB3023 Exam 1, cell bio test 1 FAU
Theisen, CH.1: Cells and Genome

What does controlled and selective expression of genes allow? - - development of multi-cellular
organisms



protein homologous found in the same organisms which have different functions are the result of... -
gene duplication events



In the A, B, C class of protein transport pump. The conformation changes that lead to translocation of
the transporter substance are caused by... - - repeated cycles of ATP binding and hydrolysis



in cells the strongest chemical interaction is? - - covalent bonds ; covalent bonds are strong,
stable, long-lasting.



hydrogen bonds are... - polar covalent, individually weak, but many bonds together can be strong.



ionic bonds are... - strong and pliable but can easily be disrupted by polar solvents (eg. water)



van der waals forces are... - individually very weak



the majority of biological catalyst are made from... - - amino acids



True regarding prokaryotic cells? - - has a cell wall

- reproduce by binary fission

- do not exist as true...

- utilize double strands for hereditary material

- do NOT package their DNA so they do NOT need histones

,Evolution of the nucleus in eukaryotic organisms has allowed... - - Segregation of DNA from other
cellular processes

- Increase the size of the DNA molecule



When a carbohydrate is oxidized it loses both ____ and ____. - - electrons and energy ; Oxidation
is the loss of electrons and energy. The atom is left with a more POSITIVE charge.



what is meant by high specificity between molecules? - - highly complementary physical shape

- highly complementary electro chemical properties



The histones used to package newly replicated DNA - - added to DNA as it is emerging from the
replication machinery



mutations within DNA coding regions... - - usually results to deleterious changes in protein
structure



DNA coding regions have important information, any mutations on these regions are most of the time
negative (bad), so it will not be beneficial.



Entropy is the measure of... - - the amount of disorder in a system



a protein secondary structure is maintained by - - hydrogen bonds



hydrogen bonds are the bonds between atoms



binding of a ligand to a specific enzyme binding site... - - involves numerous weak noncovalent
bonds



it is not a permanent binding, so it CANNOT be covalent, it has to be a weak bond in order for it to be
able to break or go back to its original form.

,Chemical analysis of DNA will reveal the following... - - Concentration of Purines equals
concentration of Pyrimidines



Because its circular, replication of prokaryotic DNA does NOT require... - - Telomerase function



Telomerase is used to stabilize the ends of Eukaryotic chromosomes which are linear. Since prokaryotic
DNA is not linear, it does NOT need telomerase to stabilize its ends.



Flipping out refers to... - - The temporary separation of a base from its compliment to allow close
inspection.



activation energy is a property of... - - all types of chemical reactions



It is NOT the energy required to push a reaction in an unfavorable direction.



Universal features of all cells... - - take up matter from their surroundings

- store hereditary information

- use RNA to direct protein synthesis

- all cells use DNA

- all cells replicate their DNA

- transcribe DNA into RNA

- regulate gene expression

- synthesize proteins using mRNA as a template

- require FREE ENERGY



hydrophobic side chains on the outside of a protein will indicate... - - a mis-folded protein



Proteins are arranged with the polar heads (hydrophilic) facing outside and the nonpolar tails
(hydrophobic) facing inside.

, proteins are able to bind to which of the following types of biological molecules - - amino acids,
sugars, nucleotides, lipids, are basis for most reactions in cells. All proteins are able to bind to one or
more molecules, often other proteins and bound substances such as ligands or substrates.




many protein catalyzes utilize both acids and bases by... - - using properties of both
simultaneously



hydrogen bonds are common in cells because.... - - many of the covalent bonds involving
hydrogen are polar.



Water constitutes approximately 70% of the weight of every kind of cell.



introns are... - - noncoding regions of mRNA molecule



Introns are the noncoding regions on DNA and Extrons are the coding regions on DNA



The processes of replication will be best described as... - - a fast error prone process that relies on
repair mechanisms



retroviruses... - - code for an enzyme called reverse transcriptase

- code for protein which which provide for a protective coding

- code for global genetic elements



which of the following will involve an unfavorable reaction? - - pyrimidine dimerization



which of the following constitutes a horizontal transfer of DNA? - - actuation of environmental
DNA by bacteria cell



the enzymatic activity of many proteins can be altered by addition of phosphate group by class of
enzymes called... - - Kinases
