Deoxyribonucleic acid, or DNA is a genetic code that determines the characteristics of a living organism. DNA is a large molecule shaped as a double helix, or twisted ladder. It is made of repeating units called nucleotides. Unlike RNA, DNA does not have uracil, but does have thymine, and the other bases (adenine, cytosine, and guanine). DNA is very important for when it comes to transferring hereditary information. Hereditary material, or “information” is from the parents of the offspring. It is information passed down from generation to generation and makes the human race unique. Without unique DNA, the human race could become extinct in an instant.
The discovery of the double helix structure of DNA was discovered by mainly by

DNA is used to determine paternity and solve crimes by using the latest DNA technology. DNA fingerprinting is a test used to identify and evaluate the DNA in a person’s cells. Because every human has a unique fingerprint, it is easy to tell who was at a crime scene when remnants of cells are left. DNA testing can confirm paternity by looking at pedigrees, or taking blood samples. With the DNA technology that is available today, police are able to narrow down suspects in a crime scene. Scientists are now able to discover biological family members that are missing and help with problems like inheritance and child custody. It also helps with adoptions and child support. New DNA technology is now even able to find the probability of having a child with a biological disease.
A mutation is a change in the DNA sequence code that can result in a genetic malfunction. Mutations can affect a single base pair, or a large segment of multiple genes. Gene mutations can be classified into two major groups; hereditary and acquired. Hereditary mutations are inherited from a parent and are throughout a person’s life, like downs syndrome and sickle cell anemia. Down syndrome, also known as trisomy 21, is caused by an extra copy of a genetic material on the 21st chromosome. This causes the child to have upwardly slanted eyes, flat
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 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
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.
DNA, Deoxyribonucleic Acid, is the basic structure for all life, it is the blueprint, the instruction manual, on how to build a living organism. DNA is made up of four nitrogen bases, adenine, thymine, cytosine, and guanine which are connected by sugar-phosphate bonds. Through a process called Protein Synthesis, the nitrogen bases are the code for the creation of amino acids. Essentially, DNA makes amino acids, amino acids make proteins, proteins make organisms. This process has been taking place for much longer than scientists have been able to document. Those scientists are called geneticists and their field is genetics.
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(deoxyribonucleic acid) is a molecule that carries the instructions for reproduction, growth, development, and functioning for all known living organisms.
Altering the DNA sequence is the primary source of all genetic disparity. The allelic variants that arise from one generation mutating which then are transmitted to make evolution possible. According to the Genetics Home Reference (2014), “a gene mutation is a permanent change in the DNA sequence within a given gene”. These mutations can vary greatly as they range in size. There are two main ways in which these mutations can occur. They are referred to as inherited mutations and point mutations. An inherited mutation is a gene mutation which is passed through family or generations it is inherited when the DNA of a cell carries a change that has been passed down from the mother or father of the person. This mutation is due to heredity. People
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 a long curved structure, made up of pairs of four specific bases: adenine, guanine, cytosine, and thymine, is the repository of a code from which all of our cells are made. The code is made up of base pairs which look like the

International adoption rates have increased dramatically since 1971, with 330,000 children being adopted from countries outside of the United States (US Department of State, 2005). With this increase in adoptions, there has also been an increase in the diversity of American families. Children are being adopted from 100 different countries, specifically China, Russia, South Korea, and Guatemala (US Department of State, 2005), so the face of the all-American family is beginning to shift. Researchers have since begun analyzing the parenting styles of these adoptive parents and inquired how color-blindness and social culturization effects the well-being of the adoptees.
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 is a hereditary material, or molecule that gives an organism the things it needs in order to live, survive, develop and reproduce. It’s made of of molecules, called nucleotides. Every nucleotide has a sugar group and nitrogen base. The nitrogen base has four different bases, adenine, cytosine, guanine and thymine. The way these four bases line up determines the DNA’s genetic code. The way the bases in the DNA forms genes, is by telling the cell to make proteins. DNA has to be coiled tightly inside of the cell, because it is so long. Being coiled so tightly creates a wall on the outside of the cell, called a chromosome. A chromosome is a thread like structure of a nucleic acid and proteins found in the nucleus of most living cells, carrying
