Making more copies of DNA from a single desired DNA is called DNA amplification or DNA proliferation. The prepared DNA has to be amplified to get enough number of copes of DNA for gene manipulation. Two methods have been followed to amplify the DNA. They are gene cloning and PCR (Polymerase Chain Reaction). Gene cloning : Production of multiple copies of a desired DNA in vivo by constructing an rDNA and introducing  it into a bacterium, is called gene cloning.

Key Difference – Lactobacillus vs Bifidobacterium   In the context of modern microbiology, different bacterial species with symbiotic associations with the human body are currently being investigated to identify different beneficiary factors. These bacterial species provide different benefits to the host that include the upregulation of host growth and development. Lactobacillus and Bifidobacterium are such two bacterial species that are recognized as probiotics. Probiotics are beneficiary bacteria that are present in the gut microbiota that provides different benefits to the host.

ionic equation: An equation in which dissolved ionic compounds are shown as free ions. molecular equation: An equation in which the formulas of the compounds are written as though all substances exist as molecules. What is a ionic equation?Similar to a molecular equation, which expresses compounds as molecules, an ionic equation is a chemical equation in which the electrolytes in aqueous solution are expressed as dissociated ions. ... Additionally, the net charge is the same on both sides of the equation.

Static vs Dynamic Modelling Any system can be described using a mathematical model that contains mathematical symbols and concepts. Mathematical modeling is the name of the process that is undertaken to develop a model for a particular system. It is not just life sciences but also social sciences that make heavy use of these mathematical models. In fact, it is in an art subject like economics that these mathematical models are used extensively.

Tailstock A tailstock, also known as a foot stock, is a device often used as part of an engineering lathe, wood-turning lathe, or used in conjunction with a rotary table on a milling machine. It is usually used to apply support to the longitudinal rotary axis of a workpiece being machined. A lathe center is mounted in the tailstock, and inserted against the sides of a hole in the center of the workpiece.

The main difference between Blackbox and Whitebox testing is that blackbox testing checks the functionality of the system without considering the internal structure of the system while whitebox testing checks the internal structure of the system including the program code. Software testing is a major phase in software development. It is the process of verifying and validating to ensure that the software is working as expected. Avoiding software testing can result in delivering products with bugs to the end users or the customers.

The main difference between ectomycorrhizaeand endomycorrhizaeis that the hyphae of the ectomycorrhizae form a sheath around the root from the outside, whereas the hyphae of the endomycorrhizae enter the cells of the root. Ectomycorrhizaeand endomycorrhizae are two types of mycorrhizal fungi, which are the symbiotic fungi with the roots of plants.Ectomycorrhizae form a Hartig net between the cells in the root cortex while endomycorrhizae forms branched hyphae called arbuscles inside the cells in the root cortex.

The most prominent difference between antelopes and deer is that male deer have antlers which they shed and grow every year while antelopes have horns that are permanent. Another difference is that deer antlers are branched and antelope horns are not. Antelopes belong to family Bovidae (as do sheep, goat and cattle), while deer belong to family Cervidae. Both are even-toed ungulates (hoofed animals) and ruminant mammals. Comparison chart Differences — Similarities — Antelope versus Deer comparison chart AntelopeDeerIntroduction (from Wikipedia) Antelopes are several even-toed ungulate species in Africa and Eurasia, comprising a miscellaneous group within the family Bovidae, encompassing those Old World species that are neither cattle, sheep, buffalo, bison, nor goats.

Capacitor and Resistors are two very important passive components of an electric circuit. Both of them play different roles in determining how the circuit behaves and are connected through conductive wires through which electricity pass. Capacitor vs ResistorThe main difference between Capacitor and Resistor is that while a capacitor is an electronic device used to store electrical energy in the form of charges, a resistor is an electronic device used to resist or block the flow of current in a circuit.

Down vs Feather   Down and feather are words that can be seen mentioned on products like pillows, duvets, comforters, and even jackets that we wear during winters. Is there a difference between a pillow made up with down and a pillow containing feathers. We all know that down and feather come from geese and ducks. We also know that these soft objects are used inside pillows, to make them soft and also to provide us warmth.
