The stability can be measured in various ways; a common way is the melting temperature (also called T m value), which is the temperature at which 50% of the double-strand molecules are converted to single-strand molecules; melting temperature is dependent on ionic strength and the concentration of DNA. As a result, it is both the percentage of ...

E-learning system, collaboration of students on project based learning, and technological skills for future results in motivation of students. [citation needed] Although these previous examples only show a few of the positive aspects of technology in society, there are negative side effects as well. [6]
The relationship between education and technology has emerged as a pivotal aspect of contemporary development, propelled by rapid expansion. internet connectivity and mobile penetration. [1] Our world is now interconnected, with approximately 40% of the global population using the internet, a figure that continues to rise at an astonishing pace ...
The usage of recombinant DNA technology is a process of this work. [1] The process involves creating recombinant DNA molecules through manipulating a DNA sequence. [1] That DNA created is then in contact with a host organism. Cloning is also an example of genetic engineering. [1]
Before the DNA can be analyzed, it must be extracted from the cells and purified. There are many ways this can be accomplished, but all methods follow the same basic procedure. The cell and nuclear membranes need to be broken up to allow the DNA to be free in solution. Once the DNA is free, it can be separated from all other cellular components.
The DNA band can also be cut out of the gel, and can then be dissolved to retrieve the purified DNA. The gel can then be photographed usually with a digital or polaroid camera. Although the stained nucleic acid fluoresces reddish-orange, images are usually shown in black and white (see figures). UV damage to the DNA sample can reduce the ...
