DNA replication is a biological process that occurs in all living organisms and copies their DNA; it is the basis for biological inheritance. The process starts when one double-stranded DNA molecule produces two identical copies of the molecule. The cell cycle (mitosis) also pertains to the DNA replication/reproduction process. The cell cycle includes interphase‚ prophase‚ metaphase‚ anaphase‚ and telophase. Each strand of the original double-stranded DNA molecule serves as template for the production

electrophoresis machine. An electric current is run through the machine and the different sized molecules form bands on the gel matrix. In visualization‚ the gel is dyed so the results become present. This is used in modern crime labs‚ figuring out DNA‚ which plays a key role in many criminal trials. The researcher completed this experiment to figure out who committed the murder using gel electrophoresis. The researcher followed five steps in this experiment; First was placing the gel in the electrophoresis

Regarding to an article by Investopedia‚ the Power-Distance Index (PDI) is an index developed by Dutch sociologist Geert Hofstede that measures the distribution of power and wealth between people in a nation‚ business or culture. The power-distance index seeks to demonstrate the extent to which subordinates or ordinary citizens submit to authority. The power-distance index figure is lower in countries or organizations in which authority figures work closely with those not in authority‚ and is higher

Extraction of DNA Molecule of an Onion In an Aqueous Solution By: Introduction DNA(deoxyribonucleic acid) is found in every living organism. It provides the information and instructions to build and regulate cells in organisms. The information it contains is used when organisms are being reproduced. It is made up of two polynucleotide chains known as DNA strands. Within the two chains there are four nucleotide units: adenine‚ thymine‚ cytosine‚ and guanine. Materials and Methods An onion

determine the unknown DNA plasmid using restriction enzymes and conducting electrophoresis finally comparing the resulting fragments with the known restriction map. In this lab‚ it succeeds in showing the fragments. In this report we will discuss the‚ results‚ limitations and possible errors. Introduction In biology restriction enzymes are used in several ways to modify and manipulate DNA molecules. One common use is to compare pieces of DNA from one that is unknown‚ with fragments of DNA from another source

Efficient‚ clean and less expensive to implement than most other alternatives‚ combined cycle power plants offer a blend of operational attributes that makes it the best choice for power production. The generated power and efficiency of gas turbine plants depend on the temperature of the inlet air. At high ambient temperatures‚ a power loss of more than 20%‚ combined with a significant increase in specific fuel consumption‚ compared to ISO standard conditions (15 C)‚ can

the Refractive Index? The aim of this experiment is to investigate the relationship between the refractive index and the wavelength. We will be testing 5 different wavelengths: 630nm (red)‚ 570nm (yellow)‚ 532nm (green)‚ 445nm (blue) and 405nm (violet). Figure 1 Figure 1 What is the refractive index? The refractive index is the measurement of how hard it is for light to pass through a certain substance‚ thus affecting the speed of light. By knowing the refractive index of a substance

and weight. Please also do not forget to define the actual term BMI! The body mass index (BMI) is of a measurement that was introduced in the early 19th century in order to categorize the entire population’s weight problems. The BMI is a statistic that is used to classify people’s weight as underweight‚ normal weight‚ overweight or obese. The formula that is used to calculate ones BMI is that the metric system will divide ones weight in kilograms by ones height in squared meters. Then the units

strands of DNA double helix are separated‚ each can serve as a template for the replication of a new complementary strand‚ producing two daughter molecules each of which contains two DNA strands with an antiparallel orientation. The enzymes involved in DNA replication process are template-directed polymerases that can synthesize the complementary sequence of each strand with extraordinary fidelity. This complex leads to the local denaturation and unwinding of an adjacent A + T rich region of DNA. The interaction
