Biotechnology Quizzes Online & Trivia

Biotechnology is an amalgamationof all the sciences and uses highly principled techniques to either enhance the functioning and productivity of an already existing phenomena or to invent new things and phenomena by manipulating theorganisms n the micro level. In short, it is a field where we can makebig changes using small organisms.

The correct answer to this question is D. Polymerase chain reaction (PCR) is a common laboratory technique used to make many copies of a particular region of DNA. Typically, the goal of PCR is to make enough of the target DNA region that it can be analyzed or used in some other way. For instance, DNA amplified by PCR may be sent for sequencing, visualized by gel electrophoresis, or cloned into a plasmid for further experiments. Polymerase chain reaction is used in many areas of biology and medicine, including molecular biology research, medical diagnostics, and even some branches of ecology.

B. A vector is a DNA molecule used to carry additional genetic material into a cell. A vector that carries foreign DNA is called recombinant DNA. There are four types of vectors including cosmids, viral vectors, plasmids, and artificial chromosomes. The most common vectors are plasmids that are used for cloning, although some of them are designed specifically for cloning. Restriction enzymes are used to cut DNA, and these are found in bacteria, which eliminates choice A. Polymerase chain reaction is used to make millions of copies of DNA, which is the definition of choice D.

Herbicide this answer can also be option c because herbicides are very expensive....

Gel electrophoresis is a purification process whereby different proteins are separated according to their molecular weight. The charged molecules are aligned and a charge is applied that causes the molecules to move according to their weight. This separates the different fragments of the DNA according to the length and the different electrical charges. As the molecular weight so a specific protein is constant in different people, it allows the delineation of specific constituents of a mix. In separating DNA fragments, the electrical charge allows the DNA to separate according to the length and the electrical charges. This allows the assessment of different DNA fragments to find specific genes.

But not all organisms use DNA, some use RNA. This question is wrong

Biotechnology is the practical application of biological study. It uses biology to solve problems and develop products that will help the biological systems. The most prominent area of biotechnology is the production of therapeutic proteins through genetic engineering. In the future synthetic biology may reveal new information about the machinery of life, and that is a research area that many find exciting.

Biomechanics is an academic field combining the study of biology with the study of engineering focussing upon the way the human body moves. Biotechnology is the practical outcome of such study, applying the findings of biomechanics to problems of the human body or biological systems, and attempting to find practical solutions. One example is prosthetic limbs and refining these further, another is genetic engineering in the field of medicine.

Biotechnology has provided enormous benefits in numerous applications. Perhaps genetic engineering will prove to be the most outstanding. However, biotechnology scientists have produced an application that integrates cancer profiling data so that a large volume of cancer types, subtypes, and experiments can be assessed online. This will considerably speed up diagnosis and decision making over treatment, narrowing the gap between original consultation and onset of relevant treatment. This is one example, but there are no doubt many of similar significance.

Certainly biotechnologists would feel that biotechnology is the most useful. It is always easier to admire the practical outcomes of research, ones that can be directly witnessed by others, rather than the painstaking research over many years that has enabled the technology to be developed. Therefore, the biologists and engineers and biomechanists play as large a part in useful scientific disciplines. I would say it is too difficult to give brownie points to one rather than another. They are interdependent.
