In the beginning when the first Micro RNA lin – 4 was discovered, it was thought that it was the only Micro RNA. This Micro RNA was acknowledged by genetics in the nematode Caenorhabditis elegans. This Micro RNA is related to the development of the creature with time. Quite interesting to know about this gene…

The purple flower must have the P-allele because purple is dominant. We do not know what the other allele is – P or p. Let us suppose the other allele is P. UP crossed with up (true-bred white) Gametes through meiosis: P crosses with p Fl-generation is all Up, all purple If the outcome of…

Neural transmission is the process an electrical charge undergoes as it travels from the dendrites of a neuron to the terminal end of it’s axon. Once the electrical charge reaches the terminal end of the axon, neurotransmitters are released into the synapse, allowing them to bind with dendrites of the receiving neuron. The process starts…

Questions: The main goal of a differential stain is to distinguish between gram-positive and gram-negative bacteria by utilizing distinct colors. Gram-positive bacteria will appear purple when stained, whereas gram-negative bacteria will appear pink. In contrast, a simple stain treats all microorganisms equally and enhances contrast. The key distinction between these staining techniques lies in their…
