Dna Macromolecule

Understanding DNA can take a lot of studying and confusion to even get the general idea of the concept. The structure of DNA is very complicated and complex to understand, but researchers James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin all developed the idea of the DNA structure in 1953. Deoxyribonucleic Acid is found in the nucleus of the cell. It is a double stranded molecule that contains the genetic code and is the main component of chromosomes. DNA is the blueprint of organisms. Nucleotides are the basic unit of DNA and they are made up of sugar, phosphate, and one of the four basis including adenine,

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.

The DNA contains four types base: A (adenine) and T (thymine), G (guanine) and C (cytosine). These four letters make up the genetic alphabet and they spell out the commands for every single cell and organ of the body and also determine all the characteristics of the person.

Ok let's break DNA down first. DNA stands for Deoxyribonucleic acid. Deoxyribose is referred to the absence of an O in the Carbon 2 of the ribose pentose. DNA is made up of six smaller molecules a five-carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases adenine, thymine, cytosine and guanine. The basic building block of DNA is called a NUCLEOTIDE. A nucleotide is made up of one sugar molecule, one phosphate molecule and one of the four bases. In other words, the sugar that makes DNA is ribose a pentose sugar in the case of this molecule DNA its lacking an Oxygen in its carbon 2. Nucleic is referred to its position, our DNA most anyways is located on the nucleus of our cells, the presence of this nucleus is what differs us from Prokaryotes us being Eukaryotes.

genetic information. The information is stored as a code made up of four chemical bases:

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

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 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

First, let’s begin with the DNA that the nucleus holds in chromosomes. This is a big factor in why the nucleus is such an important part of any animal or plant cell. These DNA polymer is a double helix made up of multiple nucleotides. Each nucleotide is either a guanine, adenine, thymine, and cytosine. Except only adenine will only bond with thymine, and guanine will only bond with cytosine. DNA also has a big role in the development of living

Deoxyribonucleic acid, or DNA, like proteins, is a linear macromolecule found in all living cells. In contrast to proteins, however, it is build up of only 4 different types of building blocks, called nucleotides. Nucleotides are composed of a base, being either a purine or pyrimidine group, and a 2'-deoxyribosyl-tri-phosphate. The four types of bases composing the sequence of DNA are purines and pyramidines. The sugar is a 2'-deoxy ribose which is phosphorylated at its 5' hydroxyl group. Free nucleotides contain either one, two or three phosphates representing the mono-, di-, or triphosphate form of the nucleotide, the latter being known as dATP, dGTP, dTTP, and dCTP. Single DNA strands are not stable, but associate with a second strand to

All living organisms, from amoebas to humans, have a molecular code called DNA in their cells, which instruct the activities that keep the organism alive. DNA is made up of long, twisted strands of four molecular “letters” (A, T, G, and C), which pair up according to their complementary base pairs, and their order determines how proteins — the vital molecules that perform all the major tasks in our cells — are made. (Refer to Diagram 1 to help sum up the concept.)

Deoxyribonucleic (DNA) is the molecule that hold the genetic information of living things. In our body every cell contains about 2 meters of DNA. DNA is copied every time a cell divides. Deoxyribonucleic (DNA) is made up of two polynucleotide strands. Polynucleotide strands twist around each other, forming a shape that looks like a ladder called a double helix. The two polynucleotide strands run antiaparallel to each other with nitrogenous bases this means that the stands run in opposite directions, parallel to one another. The DNA molecule consists of two backbones chains of sugars and phosphate groups. The organic bases held together by hydrogen bonds. Although bases bonded together are termed paired

The genome, all the genetic material encoded within the sequence of deoxyribonucleic acid (DNA), which is unique to each individual organism, has all the information required for a cell to sustain life. This is possible due to gene expression which is the process of the genetic code, DNA, being translated into proteins which a cell can then utilise for specific functions whether it be a unicellular or multicellular organism. Through this process there are many steps taken from the raw genetic code to the finished protein, the cell ensuring each step progresses without mistake and that the resulting protein has been

material of some viruses. RNA molecules are like DNA. They have a long chain of

Due to the DNA’s specificity, samples can be utilised for identification. DNA is a nucleic acid composed of deoxyribose sugar bound to a phosphate group and one of four nitrogenous bases (adenine, guanine, cytosine and thymine). Each section of these three components are referred to as nucleotides, which are joined to the phosphate or sugar of another nucleotide by strong covalent bonds to form a backbone. The nitrogenous bases are joined to complimentary bases of another nucleotide (adenine with thymine, guanine with cytosine) to create a double stranded molecule (Figure 2). To complete the double helical structure, the molecule coils to compact it’s contents. DNA molecules can contain up to two million base pairs, with a human genome containing approximately 3 million base pairs. The random assortment of nitrogenous bases as well as the numerous mutations within certain DNA sequences, results in genetically diverese DNA molecules and genomes between individials.
