Cone down

... from the lightsource. I could get a 100x objective cheaply enough (about $40) and have a condenser lens that gets the light in a good shaped cone to send up and a few precision photographic enlarger lenses of three strengths with irises on each to further change how the slide is lit from ...

... in general, the same restriction enzyme that is used to digest the plasmid vector is the same enzyme used to digest a dna of interest to make a cone bank. the question is BamHI is used to completely digest a plasmid while Sau3a is used to partially digest a chromosomal dna. i know that they ...

... neurons. After correct positioning in the developing nervous system, the motor neurons need to form connections with their target cells. Growth cones at the tip of the growing axons are specialised structures which move and sense environmental signals. The growth cone extends and retracts filopodia ...

actually the cause has to do with the adaptation of the eye to light. the darkness causes all the retinen in cone cells to associate with its opsin partner, leading to an increased sensitivity of the cell to intense light. When the light is turned on, it overwhelms the receptor. ...

... they reflect light from particular regions of the visual spectrum and the light that is reflected is picked up by photoreceptors in your retina. Cone shaped receptors are only found in the fovea (cones deal with color vision, detail vision and vision in high levels of light), while the peripheral ...
