Choose the correct statement of the following

a. In general, high acetyl-CoA or citrate are present, or when a high proportion of the cell’s adenylate is in the form of ATP, gluconeogenesis is favored.

b. When the level of AMP increases, it promotes glycolysis by stimulating PFK-1 by inhibiting FBPase-1

c. Phosphorylation of fructose 6-phosphate, catalysed by phosphofructokinase-2 (PFK-2)

d. Glucagon increases the cellular level of fructose 2,6 bisphosphate, stimulating glycolysis and inhibiting gluconeogenesis.

#Applied Microbiology

Read the following statements regarding the steps of a standard PCR cycle and choose the correct option.

Statement I: The denaturation step involves the breaking of phosphodiester bonds to separate the double-stranded DNA into single strands.

Statement II: The annealing temperature is usually set 3 -5 ⁰   C lower than the melting temperature (Tm) of the primers to ensure specific binding.

#Applied Microbiology

In the following question, a statement of Assertion (A) is followed by a statement of Reason (R).

Assertion (A): The annealing step must be performed at a significantly lower temperature than the denaturation step.

Reason (R): High temperatures destabilize hydrogen bonds, while lower temperatures favor the formation of hydrogen bonds required for primers to hybridize with the template.
