The use of DNA primers complementary to 5 ′ ending strand (which is identical to 3 ′ -ending strand sequence) which are used to close the gaps at the end of each contig. Introduction: A desired DNA segment can be amplified if at least the sequences of its end portion are known by polymerase chain reaction (PCR). PCR uses DNA polymerase enzyme which uses deoxyribonucleotides and synthesize strands of DNA using DNA template. DNA polymerase adds nucleotides to already existing strands called primers. PCR uses primers which targets sequences present at the ends such that their 3 ′ end is positioned toward the segment which is supposed to be amplified. The PCR primers are complementary to the opposite strand sequences of target DNA.

The pyruvate dehydrogenase complex catalyzes the oxidative decarboxylation of pyruvate to form acetyl CoA. E₁, E2, and E3 are abbreviations for the enzymes of the complex. Classify the enzyme names, prosthetic groups, and reactions as E1, E2, or E3. E₁ E2 Answer Bank E3 transfer of electrons to FAD and then to NAD+ transfer of acetyl group to coenzyme A formation of hydroxyethyl-TPP hydroxyethyl group transferred to lipoamide thiamine pyrophosphate (TPP) FAD lipoamide dihydrolipoyl transacetylase pyruvate dehydrogenase dihydrolipoyl dehydrogenase

Patients with pyruvate dehydrogenase deficiency show high levels of lactic acid in the blood. However, in some cases, treatment with dichloroacetate (DCA), which inhibits the kinase associated with the pyruvate dehydrogenase complex, lowers lactic acid levels. How does DCA act to stimulate pyruvate dehydrogenase activity? DCA activates pyruvate dehydrogenase kinase. DCA increases phosphorylation levels of pyruvate dehydrogenase. DCA inhibits pyruvate dehydrogenase kinase. ODCA activates pyruvate dehydrogenase phosphatase. What does this suggest about pyruvate dehydrogenase activity in patients who respond to DCA? The pyruvate dehydrogenase complex is active only when phosphorylated by the kinase. The pyruvate dehydrogenase complex is active only in the presence of the kinase. The pyruvate dehydrogenase complex is completely inactive. The pyruvate dehydrogenase complex displays some residual activity.
