(a)
Interpretation:
The number of different 8-mer sequences of DNA needs to be determined, where there are 16 possible dinucleotides and 64 possible trinucleotides and each position can be one of the four bases, corresponding to two bits of information.
Introduction:
Deoxyribonucleic acid (DNA) is a molecule consisting of two strands that twist around each other to create a double strand containing DNA directions for the development, working, growth and breeding of all recognized species and many bacteria. Also recognized as polynucleotides, the two DNA sections consist of simpler monomeric blocks called nucleotides.
(b)
Interpretation:
The number of bits of information that are stored in an 8-mer DNA sequence, in E.coli genome and in human genome needs to be determined.

Biochemistry
- B- Vitamins are converted readily into important metabolic cofactors. Deficiency in any one of them has serious side effects. a. The disease beriberi results from a vitamin B 1 (Thiamine) deficiency and is characterized by cardiac and neurological symptoms. One key diagnostic for this disease is an increased level of pyruvate and α-ketoglutarate in the bloodstream. How does this vitamin deficiency lead to increased serumlevels of these factors? b. What would you expect the effect on the TCA intermediates for a patient suffering from vitamin B 5 deficiency? c. What would you expect the effect on the TCA intermediates for a patientsuffering from vitamin B 2 /B 3 deficiency?arrow_forwardPyruvate is accepted into the TCA cycle by a “feeder” reaction using the pyruvate dehydrogenase complex, resulting in acetyl-CoA and CO2. Provide a full mechanism for this reaction utilizing the TPP cofactor. Include the roles of all cofactors.arrow_forwardMap out all of the metabolic pathways in the liver cell. Draw out the structures and names of all compounds neatly by hand and the pathways responsible for metabolizing them. Some examples are: Glycolysis/gluconeogenesis, PPP, Glycogenesis/glycogenolysis, Krebs, ETC, selectamino acid pathways (Ala, Glu, Asp) Lipogenesis/lipolysis. Citrate/MAS/glycerol phosphate shuttlesystems, and the Cori/Glc-Ala cycles. Rules:-Draw both a mitochondrial area of metabolism and a cytoplasmic area of metabolism.-Draw the liver and its roles in glucose recycling (Cori cycle/Glc-Alanine recycling)-Avoid drawing the same molecule twice (except for separate mitochondrial/cytoplasmic populations. i.e. Design the PPP/Glycolysis so that GAP is only drawn once)-Label Carbon 4 of glucose and highlight where you would expect to find it in EVERY compound in whichit is present.-Have one or two locations for NADH/NADPH/ATP/GTP/CoQH2 – many arrows will come to/from thesespots.arrow_forward
- a. Draw the Krebs Cycle and show the entry points for the amino acids Alanine,Glutamic Acid, Asparagine, and Valine into the Krebs Cycle. (Include name of Enzymes involved) b. How many rounds of Krebs will be required to waste all Carbons of Glutamic Acid as CO2? (Show by drawing out the mechanism that occurs)arrow_forwardThe malate-aspartate shuttle allows malate to be exchanged for aspartate acrossthe inner mitochondrial membrane. (a) Describe the role of the malate-aspartate shuttle in liver cells under HIGHblood glucose conditions. Be sure to explain your answer. (b) Describe the role of the malate-aspartate shuttle in liver cells under LOW blood + glucose conditions.arrow_forward(a) Write out the net reaction, calculate ∆E ̊' for the reaction, and calculate the standard free-energy change (∆G°') for the overall oxidation/reduction reaction. (h) How many moles of ATP could theoretically be generated per mole of FADH2 oxidized by this reaction, given a ∆G ̊' of ATP synthesis of + 31 kJ/mol? How many moles of ATP could be generated per mole of FADH2 oxidized by this reaction under more typical cellular conditions (where ∆G' of ATP hydrolysis is ~ -50 kJ/mol)? Be sure to show your work and explain your answer.arrow_forward

Phosphate is a substrate for Complex V (the ATP Synthase), the enzyme that couples the synthesis of ATP to the H+ gradient formed by the electron transport chain. (a) Bongotoxin is a hypothetical compound that inhibits the phosphate translocase of the inner mitochondrial membrane. Explain why electron transport from NADH to O2 stops when bongotoxin is added to mitochondria (i.e., why do electrons stop flowing through the electron transport chain even with an abundance of NADH and O 2 present). What effect will the addition of the weak acid dinitrophenol (DNP) to the cytosol have on electron transport in bongotoxin-inhibited mitochondria? Be sure to explain your answers.

(b) If dinitrophenol (DNP) is added to the mitochondria in (a) above, what effect would DNP have on the yield of ATPs per O2 reduced from TMPD/ascorbate electrons?arrow_forward
- Sodium fluoroacetate (FCH2CO2Na) is a very toxic molecule that is used as rodent poison. It is converted enzymatically to fluoroacetyl-CoA and is utilized by citrate synthase to generate (2R,3S)-fluorocitrate. The release of this product is a potent inhibitor of the next enzyme in the TCA cycle. Show the mechanism for the production of fluorocitrate and explain how the molecule acts as a competitive inhibitor. Predict the effect on the concentrations of TCA intermediates.arrow_forwardIn three separate experiments, pyruvate labeled with 13C at C-1, C-2, or C-3 is introduced to cells undergoing active metabolism.
