#Unit 7. System Physiology – Animal
  1. neural projections from taste receptors reach different parts of the brain than the neural projections from olfactory receptors
  2. the single area of the cerebral cortex that receives smell and taste signals can distinguish tastes and smells by the pattern of action potentials received
  3. tastant molecules are airborne, whereas odorant molecules are dissolved in fluids
  4. distinguishing tastant molecules requires learning, whereas smell discrimination is an innate process

The use of wild type pTi as a vector presents the following three problems.
1. Presence of oncogenes (iaaM, iaaH and ipt) in T-DNA, which causes a disorganised growth and a loss of regeneration potentiaLof the cells having T-DNA in their genomes.
2. Their large size makes the handling procedures during cloning tedious and cumbersome.
3. A general lack of unique cloning sites within the T-DNA, which are needed for the insertion of DNA segments to be cloned
In the above mention’s problems, 1 and 3 can removed by disarming and creating MCS, to overcome from 2nd problem need to develop

The pL promoter is controlled by the cl repressor protein of bacteriophage A. In practice, a temperature-sensitive mutant of the cl repressor, cl857, is generally used to regulate pL-directed transcription. Cells carrying the temperature-sensitive cl repressor are first grown at 30°C, and 42°C
