A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode, which emits light when activated.When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons.

Stereo-isomers cannot be differentiated by just seeing at their chemical formula..
It is due to the spatial orientation of different groups attached to an atom with respect to one another...
They are generally differentiated by passing polarized light through them and then finding whether an isomer is rotating the plane of light in right or left direction and by what magnitude..

Stereoisomers are isomers that differ in spatial arrangement of atoms, rather than order of atomic connectivity.One of their most interesting type of isomer is the mirror-image stereoisomers, a non-superimposable set of two molecules that are mirror image of one another. The existence of these molecules are determined by concept known as chirality. Stereoisomers contain different...  more»

Liver converts the nutrients in our diets into substances that the body can use, stores these substances, and supplies cells with them when needed. It also takes up toxic substances and converts them into harmless substances or makes sure they are released from the body. The liver's another main job is to filter the blood coming from the digestive tract, before passing it to the rest of the body. The liver also detoxifies chemicals and metabolizes drugs. As it does so, the liver secretes bile that ends up back in the intestines. The liver also makes proteins important for blood clotting and other functions. «less

Almost whole bio-chemistry relies on different data. And statistics is required for arranging the data and inferring different results or facts from them. So, if you are just a basic student of biochemistry, you need not worry about the same, statistics is required only in advanced stages of biochemistry, where you are giving a thesis or you are in the process of pursuing a PhD from it....

When DNA is heated the double strands unwind and separate into single strands through the breaking of the hydrogen bonding between the bases. The term used to refer to this process is denaturation. Denaturation can be accomplished by other methods but in molecular diagnostic testing heat is the method of choice.

The Temperature of Melting (Tm) is defined as the temperature at which 50% of double stranded DNA is changed to single-standard DNA. The higher the melting temperature the greater the guanine-cytosine (GC) content of the DNA.

The melting temperature depends on both the length of the molecule, and the specific nucleotide sequence composition of that molecule. The guanine-cytosine pair is bound by three hydrogen bonds, while adenine-thymine pairs are bound by two hydrogen bonds. DNA with high GC content is more stable than DNA with low GC content. In PCR experiments GC content of primers are used to predict their annealing temperature to the template DNA. A higher GC content level indicates a higher melting temperature.
Formula:
Tm = 2 °C(A + T) + 4 °C(G + C) = °C Tm «less

Supriya Nath replied | 20/06/2016

Ok..the previous answers are true but without knowing the ' GC' content one can use 95 to 92 degree celsius for eukaryotic DNA. We use that temp. while performing PCR.
