Discussion

13798.	Question : Neuroplasm of neuron contains high K^(+) concentration, during maintenance of action potential.
Answer» Solution :For the maintenance of action potentialion PUMPS and ion-channels play significant ROLE when from `Na^(+) - K^(+)` pump, `3Na^(+)` IONS are pushed out from neuroplasm, `2K^(+)` ions enters inside, so CONCENTRATION of `K^(+)` ion increases inside neuron.

Discussion

13799.	Question : Neurospora an ascomycetes fungus has been used as a biological tool to understand the mechanism of plant genetics much in the same way as Drosophila has been used to study animal genetics. What make Neurospora so important as genetic tool ?
Answer» Solution :NEUROSPORA (PINK bread mould) is often called Drosophila of PLANT kingdom. It is haploid in NATURE and every MUTATION can express immediately. Several characteristic of this organism make it ideal to be used for genetic studies. Some of these features are following: (a) Reproduces quickly (b) Easy to culture (c) Can survive on minimum media.

Discussion

13800.	Question : Neurospora, an ascomycetes fungus has been used as a biological tool to understand the mechanism of plant genetics much in the same way as Drosophila has been used to study animal genetics. What makes Neurospora as a genetic tool? Justify your answer.
Answer» Solution :Neurospora is used as a biological tool to understand the mechanism of plant genetics by the scientists. It because of the following reasons. 1. It is haploid and so recessive traits can be studied easily. 2. A LOT of INFORMATION is available about its genome. 3. As a RESULT of sexual reproduction, it produces eight ascospores which show a specific arrangement. This helps to study recombination.
