Biotechnology Webquest Answers Key
In this webquest, we explored the fascinating field of biotechnology and delved into some of its key applications and breakthroughs. Biotechnology is a multidisciplinary field that combines biology, chemistry, genetics, and engineering to create new products and technologies that improve our lives.
One of the questions in the webquest required us to identify the key components of a DNA molecule. The answer to this question is that DNA is made up of nucleotides, which consist of a sugar (deoxyribose), a phosphate group, and a nitrogenous base (adenine, thymine, guanine, or cytosine). These nucleotides are connected by phosphodiester bonds to form the characteristic double helix structure of DNA.
Another question in the webquest asked us to explain the process of genetic engineering. Genetic engineering involves manipulating the DNA of an organism to introduce new traits or characteristics. This is done by isolating a specific gene of interest, using restriction enzymes to cut the DNA at specific points, and then inserting the gene into the DNA of the target organism using a vector, such as a plasmid. Once the gene is inserted, it can be expressed and the desired trait or characteristic is produced.
In addition to genetic engineering, biotechnology also encompasses other important applications, such as DNA sequencing and cloning. DNA sequencing allows us to determine the exact order of nucleotides in a DNA molecule, while cloning involves creating an exact copy of an organism or a specific gene. These techniques have revolutionized fields like medicine, agriculture, and forensic science.
