What Is The Purpose Of A Polymerase Chain Reaction

Decent Essays
A. What is the purpose of a polymerase chain reaction (PCR)? List the four main components of a PCR. (2 points)
The purpose of a PCR is to make large amounts of DNA segments from just a specific DNA sequence. This method is used to scientifically prove if a suspect of committing a crime is truly the person who committed the crime. The four main components of a PCR are: DNA from a sample, nucleotides A, T, G, C, DNA polymerase, and primers.

B. What is gene expression? List the two steps of gene expression and where they occur in the cell. (2 points)
Genes are genetic codes or also known as sections of DNA. In order for this genes to be useful to a living organism, they need to be turned into useful products. The process of making these useful

    The two major uses for the information is for personal identification and for the determination of paternity. DNA can be analyzed from a variety of human samples including blood, semen, saliva, urine, hair, buccal (cheek cells), tissues, or bones. The polymerase chain reaction (PCR) is used to amplify the genomic DNA from a sample and electrophoresis is used to arrange the segment.…

    Several Advancements in technology produced a fast DNA sequencer in the 70’s, and in 1983, Karv Mullis created what is called Polymerase Chain Reaction (PCR). PCR is a very simple and inexpensive technology that is used to amplify and produce large amounts of copies of a segment of DNA. Now this has become one of the most significant scientific advances in molecular biology, PCR amplification is used every day to diagnose diseases, its also used to identify bacteria and viruses, and to match criminals to crime scenes. PCR has revolutionized the study of DNA to such an extent that Dr. Mullis was awarded the Nobel Prize in Chemistry in 1993.…

    PCR is used to magnify the 16S rRNA gene and is used in molecular biology to make thousands of copies of the magnified DNA. There are three main stages that the PCR carries out, the first is denaturing when the double-stranded DNA is separated into two strands. Second, annealing which enables the DNA primers to attach to the DNA when the temperature is lowered. Lastly, extending which is when a new strand of DNA is created by the Taq polymerase enzyme when the temperature is raised. This process is run in cycles 29 times and takes approximately 4 hours to complete.…

    The Basics of Gene Expression and Control Genetics is a very diverse field of science, because it encompasses so many aspects of not only what happens inside organisms, but also how offspring relate to parents and ancestors and many other processes. Although every bit of genetics is important, many things in an organism would not be possible without the expression of genes. Through expressions of genes, organisms provide for themselves and "fulfill" what is the basis of their genetic possibility. These processes of transcriptional gene control, translational gene control, and post-translational gene control helps make key components that help an organism function in many ways.…

    DNA gives cells the potential for specific behavior, but this potential will only be realized if the gene is expressed. A gene is expressed if the DNA is transcribed into RNA and then converted into a protein. These proteins can have many different effects on the cell, such as metabolism or neurotransmission. We are now able to tell which specific genes are expressed at a particular time. Gene expression is uncommon, however, with no transcription and only the potential for a behavior as a result.…

    DNA analysis, also known as DNA profiling, testing, typing, is a process that takes genetic material and evaluates it so that it can identify individuals in a criminal investigation or in use of a forensic application. The beginning step of the performance of DNA analysis on a reference sample or person is the collection of DNA from cells. These cells can come from a blood sample or even swabbing the inside of an individual’s cheek. After it is collected, the samples are then sent to a lab for the further steps of DNA analysis. There are different methods that can be used to analyze this DNA.…

    Although there isn't always a definite answer on who did the crime, DNA technology has evolved and is a great tool to provide evidence for a case. With that said, DNA alone is not enough to find a suspect guilty or not guilty. DNA is evidence used to determine who committed the crime, how they committed the crime, or if they are innocent. In 1999, in Australia, a girl was raped, and named Frank Button as the criminal who committed the crime. The sheets and pillowcases from where the assault took place were sent to the laboratory, but not tested.…

    PCR History The invaluable molecular technique known as PCR, or the polymerase chain reaction, was discovered by a biochemist named Kary Mullis. Mullis was doing research in the early 1980s at a biotechnology company in California when he initially thought of the idea regarding PCR. PCR was developed by a combination of several techniques already in existence; the synthesis of oligonucleotides and their utilization to synthesize new copies of DNA that were specific using DNA polymerases.…

    Imagine this; a world where no one has lifelong infections or medical conditions. This might be made possible soon; however, some are afraid that parents will take it too far. With enough money, they could transform their babies to be intelligent and good looking. In my opinion, genetic engineering should be allowed, but restrictions should be in place to stop parents from making super babies. Genetic engineering is the purposeful changing of an organism's DNA.…

    Of the four organic macromolecules deoxyribonucleic acid, or DNA, is a nucleic acid. DNA is a double-stranded molecule comprised of numerous nucleotides covalently bound together. Nucleotides contain a deoxyribose sugar, a phosphate group, and one of four nitrogenous bases. The four nitrogenous bases are adenine (A), thymine (T), guanine (G), and cytosine (C). To construct DNA’s double helix, hydrogen bonds form between two complementary nitrogenous bases.…
