A new drug is developed that targets and binds to the lipid A portion of LPS from Gram negative bacterial cells. This drug shows a high degree of activity and binding in a test tube setting against purified lipid A. Based on this information,

#SCPH06 I Botany

  1. we should fast track this drug and get it out to physicians immediately to help prevent toxic/septic shock in humans.

  2. we should do some animal testing with whole Gram-negative cells and the drug before we jump to any conclusions.

  3. we should next proceed by moving to testing in a test tube using whole Gram-negative cells to see if it binds with the same strength.

  4. we should abandon the drug entirely. Binding to lipid A won't kill the bacteria, so the drug is useless to develop further. It wouldn't help humans who have septic shock at all.

In the plants, due to mutation in the mitochondrial genome causing cytoplasmic male sterility can be influenced by the nuclear gene (Rf),  which is dominant over the cytoplasmic mitochondrial genome. If a male sterile plant  is pollinated by the fertile male plant with homozygous (Rf)condition, the progeny obtained in F1 will have
