There are characteristic patterns of hydrogen bonding and of overall shape that are exposed in the major groove that distinguish an A:T base pair from a G:C base pair, and, for that matter, A:T from T:A, and G:C from C:G,

In a fluidized-bed biofilm reactor, cells are attached on spherical plastic particles to form biofilms of average thickness L = 0.5 mm. The bed is used to remove carbon compounds from a waste-water stream. The feed flow rate and concentration of total fermentable carbon compounds in the feed are F = 2 l/h and S = 2000 mg/l. The diameter of the column is 10 cm. The kinetic constants of the microbial population are r_m = 50 mg S/cm³. h and K_S = 25 mg S/cm³ . The specific surface area of the biofilm in the reactor is 2.5 cm² /cm³ . Assuming first-order reaction kinetics and an average effectiveness factor of n = 0.7 throughout the column, determine the required height of the column for effluent total carbon concentration of S_0i = 100 mg/l.

The insect ingests plant tissue containing the fatty acids, an enzyme in the gut conjugates the plant-derived fatty acid to an insect-derived amino acid to form an elicitor, When plants recognize elicitors from insect saliva induces some typical responses such as

a) Increasing Ca²⁺ levels in the cytosol and then activate an array of target proteins, such as calmodulin and other Ca²⁺-dependent protein kinases

b) In Arabidopsis, a calmodulin-binding transcriptional regulator called IQD1 was identified as an important mediator of defense responses against insect herbivory

c) overexpression of IQD1 in Arabidopsis activate the herbivore activity

d) IQD1 binds calmodulin, a major Ca2+-binding protein, in a Ca2+-dependent manner and subsequently inhibits the gene involved in glucosinolate biosynthesis
