Disease and the Environment • Understand the major functions of cells and the difference between viruses, bacteria Viruses are either naked or enveloped. Enveloped can be easily disrupted with alcohols but naked are more stable. Bacteria has different states of living. Some are free to flow while others stack up and create biofilm making them resistant • Explain...

What occurs to the two strands of the parental duplex during replication? - they separate Is replication conservative, semi-conservative, or dispersive? - semi-conservative What does it mean to be conservative? - the original DNA is kept and an exact replica is made What does it mean for DNA is be dispersive? - parts of the old and new DNA are chopped together What does it mean for DNA to be semi-conservative? - each new daughter DNA is one old strand and one new strand What was the experi...

What are the 4 nitrogenous bases? Which pair together? Correct Answer-adenine (A), thymine (T), cytosine (C), guanine (G) A->T, C->G What are the issues with these combinations: 1.) Pyrimidine + Pyrimidine = 2.) Purine + Purine = 3.) Pyrimidine + Purine = Correct Answer-1.) width of DNA too narrow 2.) width of DNA too wide 3.) width of DNA consistent with X-ray model Which bases are purines and which are pyrimidines? Correct Answer-purines: A,G pyrimidines: T,C What are...

Structure of DNA CORRECT ANSWER 5'-->3' Anti-parallel 1 ring=pyrimidine 2 ring=purine A(2) + T(1) 2 H-bonds G(2)+C(1) 3 H-bonds *G and C have 3* DNA Replication CORRECT ANSWER Semi-conservative DNA Pol replicates 1000nt/second *errors only 1/10billion bp Why does the origin (oriC) have runs of A:T base pairs? CORRECT ANSWER Easy to break apart, only 2 H-bonds

What enzymes are involved in DNA replication? - ANSWER-DNA dependent DNA polymerase is DNA replication anabolic or catabolic - ANSWER-anabolic what were the 3 competing models of DNA replication - ANSWER-- semiconservative - conservative - dispersive semiconservative DNA replication - ANSWER-each daughter DNA molecule is composed of one original strand and one new strand conservative DNA replication - ANSWER-- the parent strands separate and act as templates - then the original parent...
