Dna Fingerprinting Case Summary

Improved Essays
Case study is the study of a court case which helps us to get an insight into the real life proceeding of the theoretical knowledge of something that we have. With respect to forensic science, we can say that case study helps us to get an idea of the principles and techniques that are applied in a real case in order to obtain the results. It also helps us to understand what might be the outcome of a particular approach in terms of the legal system in a specific type of case that is looked into. Here the case of child custody with the help of DNA fingerprinting is to be analysed and considered to help us understand how DNA fingerprinting might play a vital role in proving the parents of a child in a court case.

Genetic information is contained in chromosomes of humans. Each human has 23 pairs of chromosomes in their bodies. Among them, each part of the pair is obtained from one of the parents. Genetic information is inheritable, that is, they are passed on from parents to their offspring. DNA is contained in the chromosome and is present in the nucleus of cells of human body. DNA consists of nucleotides like adenine, guanine, cytosine and thymine. In each case, adenine pairs up with thymine and guanine pairs up with cytosine to form the DNA backbone. Now in each DNA the sequence in which these nucleotides are present is what distinguishes one individual from another and is unique to everyone. It is therefore to be noted that this DNA sequence serves as an identity or fingerprint for every individual. This is the basis on which the method of DNA fingerprinting analysis is conducted. The DNA constitution of all cells present in an individual are the same and it does not change with the passage of time. Also, unlike normal fingerprinting, DNA fingerprinting of an individual cannot be altered surgically. The only exception for the uniqueness of DNA fingerprint is the case of identical twins or triplets. The chances that the DNA fingerprint found at a crime scene might be duplicated are roughly 1 in

    What followed was to establish how exactly DNA worked since this was the only way genetic engineering would be executed successfully. According to Chakravarthy (2011, part 2), Francis Crick played an important role in determining how phenotypes occurred which was then enhanced through the framework he developed for understanding DNA. It was established that nucleic acids determined the sequence of amino acids in proteins in which phenes are formed. DNA replication is often the process in which a cell divides to form two daughter cells with each containing a DNA molecule thereby facilitating its transmission from one cell to another. This ensures that each daughter cell has one DNA molecule from the parent cell together with a synthesized strand.…

    These traits are often passed from a parent cell to its offspring. This branch of biology is know as genetics. DNA also possesses a unique structure that allows it to perform all these actions. DNA is composed of hydrogen ,carbon, nitrogen, oxygen, and phosphorus. The monomers that make up nucleic acids are called nucleotides.…

    Usually genetic strings are considered for any of the following three strings. 1. DNA strings: Known as DeoxyriboNucleic Acid (DNA). DNA is the main reason behind functioning and development of all living organisms. Usually, DNA molecule looks like a double helix because it contains two biopolymer strands arranges such that they looks like they are coiling around each other.…

    DNA is part of living things and if someone looks like their parent this is because they have the same Genes. Every living organism contains DNA and Genes, but the question is what is DNA and genes? Well according to the prior research as stated, DNA and genes have many uses, from a single cell, to fossils, diseases, and to ancestors. Deoxyribonucleic acid, or in other words, DNA is just…

    A part of RNA that is produced by an enzyme binds to the end of the beginning strand. RNA (primer) is the starting point for DNA synthesis. RNA primase is used to add the first nucleotide because polymerase are only able to add to growing strands. On each strand of DNA there is a sequence of nucleotides. The nucleotides is basically the place where the synthesis of a new strand will be made.…

    B. DNA Fingerprinting Principle The genome of human contains 3 billion base pairs, and they are organized in a specific sequence that gives us a unique identity. 90% of the DNA is same in all of us. DNA fingerprinting depend on the rest 10% difference in the human DNA. In DNA fingerprinting they match the uncommon sequence of humans with the suspect's unique sequence. Procedure • Obtaining a sample of DNA from the cells.…

    The Structure and Replication of DNA Introduction The structure and replication of DNA is important for organisms to develop and survive as it what has the control over all of bodies functions. DNA is converted in to messages that are used to produce proteins molecules, important for bodily functions. Without DNA genes would not be able to performs tasks such as telling the body how to create proteins which in turn would not allow proteins to create enzymes, hormones and other important chemicals. Structure Deoxyribonucleic acid or DNA is a chemical that carries all of the genetic information in all living organisms, however it is organised differently in each species. Depending on how each organism organises their DNA they are put in to…

The chromosomes condense and become compact at the time of every nuclear division. At this point, they are visible under the microscope. Meiosis…

    While mitosis, an asexual process, is required for the growth, development, and repair of a cell, meiosis, a sexual process, creates genetic diversity through sexual reproduction. Mitosis can occur in any organism, but meiosis only occurs in humans, animals, plants, and fungi. Another difference between mitosis and meiosis is that the daughter cells produced by mitosis are genetically identical, unlike the daughter cells produced by meiosis which are genetically different. Crossing over, which is the process of the exchange of genetic material between homologous chromosomes, only occurs in meiosis during prophase I, because homologous chromosomes are not present in mitosis. In mitotic metaphase, individual chromosomes composed of two identical sister chromatids line up in the middle of the cell, but in metaphase I, homologous chromosome pairs, which consist of four genetically different sister chromatids, line up in the middle of the cell.…
