What is Lycopodium spore method of analysis?
It is an important technique for powdered drug ,especially when chemical & other method fail as accurate measure of quality. Lycopodium is composed of spores of lycopodium elavatum.I. Each spore is tetrahedral in shape, The base is rounded and the threeside wallmakes the three well marked covering ridge, which join one other at filled with fixed oil. The spore are exceptionally uniform in size(25µm) and the shape tetrahedral so that one can always know that a definite no. of spore present in particular weight of lycopodium. On an average 94000 spores per mg of powdered lycopodium are present. Using this figure one can calculate the weight of any number of spores under any condition underthe microscope.
How do unsaturated fatty acids in the glycerophospholipids affect the structure of the Cell Membrane?
Because of the kinks in the carbon chains at the cis double bonds of unsaturated fatty acids, the glycerophospholipids do not fit closely together. As a result, the lipid bilayer is not a rigid, fixed structure, but one that is dynamic and fluid like.
Does the greater number of saturated fatty acids a membrane contains the more fluid it is?
Saturated fatty acids have no double bonds and therefore no 'kinks' in their structures. These would mean that these fatty acids can pack more closely than unsaturated fatty acids and cause the membrane to be LESS fluid.

Translate the mRNA by dragging the amino acid and tRNA?
Messenger RNA or mRNA comes from the gene. Gene is present in the chromosome of the cell. This messenger RNA comes with the sequence of amino acids codes. Also called as codons. The transfer RNA or tRNA brings in the amino acids. The messenger RNA directs the the type of amino acid, that has to be fixed in. The sequence of the amino acids is meticulously fallowed. If single amino acid is in short supply, then the entire chain is broken down. This is how you get the protein with specific sequence of the amino acids. The number of permutations and combinations of say 100 amino acids, is beyond the human brain to comprehend.
Difference between volatile oil and fixed oil?
volatile oils:-These are volatile at room temperature & are usually obtained by distillation.When evaporate do not leave any spot.These cannot be saponified.These are mixtures of cleoptenes & stearoptenes.Fixed oils:-Non volatile at room temp & can be obtained by special extraction process.These leave spot after evaporation.These can be saponified.These are esters of higher fatty acids & glycerin.
