20th Century DNA Research

Throughout the early 19th and 20th century, many scientists have studied deoxyribonucleic acids in order to attain higher understanding over the matter. Johann G. Mendel had figured out and understood the laws of heredity. Friedrich Miescher amazingly discovered DNA in 1869, even though scientists did not understand DNA was the genetic material

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.

Improper forensics, bad lawyering, snitches, unqualified “experts,” eye witness misidentification, false confessions, and mishandled evidence are all just a few reasons for wrongful convictions in the justice system. However, the authors of Actual Innocence: When Justice Goes Wrong and How to Make it Right, discuss how DNA is a main factor into “actually innocent” people. Throughout this book we learn stories about those who were wrongfully convicted and later proven guilty for reasons such as DNA testing. While this proves to us that not everyone convicted is guilty, it points out many other errors in the criminal justice system as well.

DNA is made up of genes, which are small portions of the DNA strand. Genes create cellular protein needed for the body to function. DNA not only creates cellular proteins, but also has the instructions for when and where they will be made. (Racenis 2)

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.

DNA is a self-replicating material that's present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information. The shape of DNA is a double helix, the sides are made of alternating sugar and phosphate molecules. The sugar is deoxyribose. The rungs of the ladder are pairs of 4 types of nitrogen bases. A base pair is two chemical bases bonded to one another forming a the rungs DNA ladder. The DNA molecule consists of two strands that wind around each other like a twisted ladder. Messenger RNA (mRNA) is a subtype of RNA. An mRNA molecule carries a portion of the DNA code to other parts of the cell for processing. mRNA is created during transcription. During the transcription process, a single strand of DNA is decoded by RNA

DNA is a series of sugars linked together in a specific order. This specific order of sugars: adenine, thymine, guanine, and cytosine, with its associated base determines the genetic information that a person will have. Each parent supplies the offspring with complementary strands of DNA passed down in tight structures known as chromosomes. The DNA codes for a specific gene and the nucleotides give the exact order of amino acids/proteins. DNA has the shape of a double helix. This shape is like two spirals wrapped around each other. The shape of DNA is essential to the way in which it functions because

DNA tells us who you are. And it is the particle that stores genetic information’s. it also, tell the cell how to build the proteins in you. The DNA has to carry information from one generation of organism to the next. DNA has to put that in formation to work by determining the heritable characteristics of organism. Next DNA has to be easily copied because all of a cells genetic information has to be replicated every time a cell divides. The DNA is like a latter, the shape is called a double helix the step of the letter is made up of four bases, Adenine which is the letter A the next one is Thymine which is T, Guanine is G and Cytosine is C. so, Adenine will always bond with Thymine A=T and Guanine will always bone with Cytosine G=C. These are called nitrogenous base. So, these genetic codes will tell the cells how exactly to build a protein the structure of the DNA is called a gene. Your body read the letter C,G,T,A like a recipe. From their it builds proteins. Proteins are made up of ells, cells are made up of tissue, and tissue are made of organism like your eye and skin. So, the gene determined what you are and what you will look like. Like the color of your hair, your skin, your eyes and soo

Although DNA was initially observed by Frederich Miescher, a German biochemist near the end of the nineteenth century, the key to the structure of DNA was not discovered until almost a hundred years later. It was at that time that science realized the importance of DNA to the study of biology.

DNA is a nucleic acid that carries the genetic information in cells, it consists of two long chains of nucleotides (a nitrogenous base, a five-carbon sugar and a phosphate group) twisted into a double helix that are joined by hydrogen bonds, where between of them there are the complementary bases: that are Adenine and Thymine or Cytosine and Guanine. DNA is the structure of life; it is where all the information of how you are is.

When most people think of DNA, scientists, laboratories, and twisted ladders come to mind. In reality, DNA makes up genetic material, which makes up proteins that form much of the body and perform vital tasks. The study of DNA and genetic material is something more people should be aware of. As a society, knowing how powerful genetic research and technology are holds the possibility to help, or possibly hurt, people now and in the future.

Deoxyribonucleic acid (DNA) which is found in all living thing and one of the building blocks of the body. (1, 2, 3) The molecule is found in the nucleus of the cell and it is a double helix molecule and it looks like a twisted ladder. If it was unwound the molecule would be 6 feet in length! (2) DNA has 3 nucleotides which are sugar, base, and phosphate. (1) The four bases, which are adenine (A), thymine (T), cytosine(C), and guanine (G) and they are all Nitrogen bases and there are about 3 billion of them.(1, 2, 3, 4) Adenine and thymine always pair up with one another and cytosine and guanine always pair together. (1, 2, 3, 4) In the cell there is also the RNA which acts as the messenger for the DNA because the
