Deoxyribonucleic Acid, Or Dna Is A Genetic Code That Determines

Point Mutation: is a nucleotide base change in the DNA that is caused by mutation. It may result in the loss, addition or substitution of a nucleotide. Where a single nucleotide base in the DNA strand is altered.

DNA is the genetic material that makes up the characteristics of all living organisms. While all human DNA is very similar in nature, there is just enough differences in

Each human being has something called DNA. DNA is described as genetics and an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms. DNA constructs of two nucleotide strands coiled around each other in a ladder like arrangement with the sidepieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine and pyrimidine bases adenine, guanine, cytosine, and thymine. Each chromosome consist of one continuous thread-like molecule of DNA coiled tightly around proteins and contains a portion of the 6,400,000,000 basepairs that make up your DNA.

DNA is a molecule that has a repeating chain of identical five-carbon sugars (polymers) linked together from head to tail. It is composed of four ring shaped organic bases (nucleotides) which are Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). It has a double helix shape and contains the sugar component deoxyribose.

Every person has his or her own unique sets of DNA. DNA is a molecule that holds the genetic instructions used in the growth, development, functioning, and reproduction of organisms. The DNA coding is needed to produce proteins. These proteins are needed to catalyze reactions for cell replication. Furthermore, multiple cells create different body systems in order to maintain homeostasis.

DNA also known as deoxyribonucleic acid is a complex molecule that carries the genetic information in the cell, essential to build and maintain an organism.

DNA(deoxyribonucleic acid) is a molecule that carries the instructions for reproduction, growth, development, and functioning for all known living organisms.

DNA Fingerprinting, also known as DNA Profiling, is a method used to identify a person using DNA patterns that are specific to him/her. 99.9% of DNA is identical in every human being, but .01% is enough to distinguish between people. It is most commonly used in criminal cases to link a criminal to his/her crime scene, but is also used for paternity/maternity tests, and immigration records. Usually a skin, hair, or body fluid sample is collected from a crime scene or criminal or test candidate, then DNA is extracted and cut using enzymes that recognize patterns in DNA and run through a gel by an electric current in a process called electrophoresis (Annely).

Gene Mutations: A gene mutation is a permanent change in the DNA sequence that makes up a gene. Mutations can vary in size from a single DNA building block (Fig 2) to a large section of a chromosome. Gene mutations occur in two ways, either they can be inherited from a parent or attained during a person’s lifetime. Mutations that are passed from parent to child are called hereditary mutations. This type of mutation is present throughout a person’s life in practically every cell in the body. Mutations that take place only in an egg can cause genetic disorders when a family has no history of the ailment. Environmental factors such as radiation (Fig 8) can cause acquired mutations in the DNA

DNA is the genetic blueprint for life because it contains the instructions that oversee the development of an organism. Taking samples of DNA and analyzing them to determine if they come from the same individual is known as DNA profiling. Investigators gather items such as hair, saliva, semen and blood that could contain DNA from a crime scene. DNA profiling is also used in paternity testing, victim identification and evolution research. First, the collected DNA samples are isolated. Next, selected sequences from each DNA sample are replicated to produce a large sample of DNA fragments. Finally, the enlarged DNA samples are compared to other samples to determine whether the samples came from the same person or

Genetic mutations are permanent changes in a DNA sequences that makes up a gene. The majority of disease-causing gene mutations are unusual in the overall population. The two major classifications of gene mutations are hereditary and somatic mutations. Hereditary mutations are immediately inherited from a parent and exist throughout a person’s life. If the DNA from the sperm or egg cell contains a mutation, the resulting fertilized egg will also inherited the mutation. Somatic mutations occur by either environmental factors or when an error appears during DNA replication. Unlike hereditary mutations, a somatic mutation will not be present in every cell. Mutations typically have a negative connotation; however, they are not always harmful,

DNA fingerprinting is a technique that is used to determine how likely it is whether genetic material came from a specific person or family group. Since 99% of human DNA is identical, that means that it is only 1% of our DNA which is different, and it is that 1% that we look at when we are attempting to determine the origin of a DNA sample.

DNA stands for deoxy-ribo-nucleic acid or sometimes called a double helix (Stoyles 8). DNA is structured and shaped by the parent’s chromosomes. The DNA made from the parent's chromosomes make a child’s chromosomes. DNA has four bases they are; Adenine, Cytosine, Thymine, and Guanine (Stoyles 8). This order of the bases creates the genetic code. The bases order helps the body know what proteins it needs to make special characteristics for the child. These proteins control and make up cells, muscle movement, and thinking. When a new cell is made a new copy of DNA is formed and this process continues over and over again.
