    HOW DNA CAN BE MUTATED AND WHAT ARE THE SYSTEMS THAT CAN REPAIR BACK THE MUTATED DNA DNA mutation. Mutation are permanent heritable alteration in the base of sequence of DNA. Mutation occurs either because of spontaneous errors in DNA replication or in a meiotic recombination of as a consequence of the damaging effects of physical or chemical agents on the DNA.There are few concept in order to understanding mutation in DNA. It is known that DNA is a chemical compounds which the components are in

  • Advantage Of Dna Barcoding

    1723 Words  | 7 Pages

    The material to be used for DNA barcoding is collected from plants, fungi, animals or products made from them. The advantage of DNA barcoding is that it can be used to identify DNA sequence even from small, damaged, or industrially processed material. First, a sample of tissue is collected, preserving the specimen whenever possible and noting its geographical location and local environment. A small leaf disc, a whole insect, or samples of muscle are suitable sources. A plant material is collected

    Deoxyribonucleic acid (DNA) is a double helix structure strand which contain hereditary genetic material of living organisms. It is composed of small single nucleotides which makes a long polymer by repeating the nucleotide units. (Saender W, 1984) The nucleotide contains deoxyribose sugar, nitrogen-containing nucleotide and phosphate group which makes the DNA negative charge. In order to further study on human genomic material, the isolation and extraction of DNA is necessary to be carried out. DNA extraction

  • The Pros And Cons Of Recombinant DNA

    1486 Words  | 6 Pages

    Recombinant DNA molecules are DNA molecules formed by laboratory methods of genetic recombination to bring together genetic material from multiple sources, creating sequences that would not otherwise be found in the genome. Recombinant DNA is possible because DNA molecules from all organisms share the same chemical structure. They differ only in the nucleotide sequence within that identical overall structure.Recombinant DNA is the general name for a piece of DNA that has been created by the combination

  • DNA In Forensic Science

    1116 Words  | 5 Pages

    DNA in Forensic Science DNA is the carrier of genetic information in humans and other living organisms. It has become a very useful tool in forensic science since it was discovered. In forensic science, DNA testing is used to compare the genetic structure of two individuals to establish whether there is a genetic relationship between them. One example of the use of DNA in forensic science that is important in biology today is comparing a suspect’s DNA profile to DNA that was discovered at a crime

  • The Pros And Cons Of DNA Testing

    1571 Words  | 7 Pages

    The history of DNA testing goes as far back as the 1920s when scientists first identified blood types in humans, which was initially used for medical procedures. Through the 1990’s other relevant blood typing procedures were used to identify individuals, as in forensics, biological relationships, as well as targeting specific regions were mutations or markers are found. In the 2000’s scientist developed different types of genetic tests to identify ancestry, predisposition to genetic medical and/or

  • The Pros And Consequences Of DNA Fingerprinting

    1660 Words  | 7 Pages

    The chemical structure of everyone's DNA is the same. The only difference between people (or any animal) is the order of the base pairs. There are so many millions of base pairs in each person's DNA that every person has a different sequence. Using these sequences, every person could be identified solely by the sequence of their base DNA fingerprinting also called DNA Typing in genetics is the method of isolating and making images of sequences of DNA (deoxyribonucleic acid). The technique was developed

    1. What is DNA? DNA i.e. Deoxyribo Nucleic Acid is a material in the human body that determines the hereditary traits of a person pertaining to hair colour, eye colour, skin, body structure, viability to diseases etc. DNA is located in the cells of the human body, wrapped in structures called chromosomes. A person inherits is DNA, 50% from his mother and 50% from his father. Any genetic disorder in an individual is usually due to mutations in this DNA. It is an established fact that the each person
