Linear Macromolecules

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,

Deoxyribonucleic acid (DNA): It is helical double stranded nucleic acid made of complementary purine and pyramidines supported by deoxy ribose sugars and phospodiester structures. (5 Prime to 3 prime). Eukaryotic DNA material.

The nucleotides encompass a sugar molecule (2' deoxyribose), one among four element ring structures called bases (called A (A), purine (G), pyrimidine (C) and T (T)) and a phosphate cluster.

Structure and function in Biology is a broad concept that can be explored within a diverse range of topics across the subject matter. The following essay will be focussed mainly on the subject of Deoxyribonucleic Acid, or more commonly DNA. DNA is a highly complex, intricate and extraordinary macromolecule found within all living cells. DNA is a "biochemical noun" and can be defined as "...a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information." [Oxford Dictionary, c2016] DNA is found in the nucleus of eukaryotic cells, enclosed within a double membrane. Eukaryotic cells are multifaceted and require a high level of regulation to ensure smooth functioning. The double membrane of the nucleus allows gene expression, a key function of DNA, to be efficiently regulated.

A macromolecule is a large molecule composed of small molecular units called monomers that are linked to together in long chains called polymers. Lipids are hydrophobic, non polar macromolecules that insulate organs, store energy, and make up cell membranes. Their monomers are called triglycerides. Proteins are another example of macromolecules. Made up of monomers called amino acids held together by peptide bonds, proteins provide structural support, defense, and cell regulation. The third macromolecule that is going to be tested for are carbohydrates. Carbohydrates, such as sugars and starches, are needed for energy storage and are made up of monomers called monosaccharides.

Deoxyribonucleic Acid is the official name of DNA, which Donald Shelton notes that “DNA is the molecular structure in all

In UNIT 7 you learned about the basics structure as well as the basic functions of deoxyribonucleic acid. You learned that deoxyribonucleic acid carries an “instruction manuel” to produce proteins that are responsible for passing traits from your parents to you. As you demonstrated in the previous activity, deoxyribonucleic acid is made of four nucleotides base pairs: adenine, thymine, cytosine, and guanine. They are often abbreviated as A, T, C, and G. The uniqueness of deoxyribonucleic acid is not particularly in just these 4 subunits, but how they are arranged. In this activity you will recreate protein synthesis.

Deoxyribonucleic acid, or in its’ simple form DNA, contains the code for all characteristics of an organism which is completed by a double helix structure. The structure is made up of a back bone and the four gene groups which include thymine, adenine, cytosine and guanine. The double helix structure contributes to the cell division process

Carbon has unique properties that allow macromolecules to form. One is that carbon can form four covalent bonds. This is because of the four valence electrons it has. A carbon atom can have a triple bond with one atom and still have an extra electron to share with another atom. Carbon bonds can take on different shapes: linear, branched, or ring-shaped. Carbon also bonds with functional groups. Functional groups are molecules with unique chemical characteristics and properties. These include hydroxyl and phosphate groups. Carbon containing molecules can have multiple forms. These different forms are called isomers. These different molecules can have the same molecular formula but will have different shapes and characteristics. Structural isomers

When analyzing DNA it is important to understand it and all the chemicals that it is made of. The first thing that’s important to know is simply what DNA stands for, which is deoxyribonucleic acid. The chemical units are called nucleotides, and each nucleotide has a compound of phosphate sugar which is the backbone, and a sugar deoxyribose. The Phosphates and sugars are the same in all nucleotides but the one thing that is different would be the bases. DNA bases are cytosine, thymine, adenine, and guanine. Each base has specific partner, for example Cytosine will always pair with guanine. And Thymine will always pair with adenine.

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

Deoxyribonucleic corrosive is a particle that conveys the hereditary directions utilized as a part of the development, improvement, working and multiplication of all known living beings and numerous infections. DNA and ribonucleic corrosive (RNA) are nucleic acids; close by proteins, lipids and complex sugars (polysaccharides), they are one of the four noteworthy sorts of macromolecules that are fundamental for every single known type of life. Most DNA atoms comprise of two biopolymer strands snaked around each other to shape a twofold helix.

The Nucleic acids are seen to be linear polymers which make chains of nucleotides. In such chains, each nucleotide is made up of three components which are discussed above. These structures are further subdivided into the nucleobases that is found in the two nucleic acids. These subdivisions include: adenine, cytosine, and guanine which are all found in both RNA and DNA molecules. In contrast,

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

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.
