Exploring The Role Of Genes In Living Organisms

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,

Ribonucleic acid (RNA): It is a single nucleic acid supported by adenine, guanine, cytosine and uracil supported by ribose sugars. mRNA, rRNA and tRNA.

Deoxyribonucleic acid, or DNA as it is most commonly known, is a strand of molecules found within the cell nucleus of all living things. It is called a “genetic fingerprint” because each is different to the other and everyone, apart from identical twins, have

DNA per medical dictionary is defined as A nucleic acid that carries the genetic information in cells and some viruses, consisting of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. DNA sequences are

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.

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.

wonder what exactly is DNA? DNA is a term used for deoxyribonucleic acid and it

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.

Genes is the physical and functional unit of heredity which are made up of DNA. It carries the information of that determines traits that are passed on by the parents. There are two copies of genes which comes from each parents which is to be exact twenty chromosome from each parent to make up forty six chromosome in a baby. As by the

DNA and ribonucleic acid are nucleic acids; alongside proteins, lipids and complex carbohydrates, they are one of the four major types of macromolecules that are essential for all known forms of life. DNA is shaped like a double helix. The DNA inside a cell is packaged into a large number of individual genes, each of which contains a set of instructions telling the cell what functions to perform, as well as how to grow and divide. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Every plant and animal has its own set of genomic “instructions”, which it receives from one or more parents. This set of instructions is called deoxyribonucleic acid (DNA) and it is what allows every organism to be its own unique individual. DNA is stored in the nucleus of a cell as a chromosome. A gene is a segment on a chromosome with a particular protein sequence. These genes then code for multiple proteins that are required for cell differentiation, development and/or the sustainment of life.

DNA is an element that influence in a genetic order used in the progress and working of all known living creatures and many viruses. DNA form together with proteins and fibres to establishes the three main macromolecules essential for all recognized forms of life.

Gene – the unit or heredity occupying a particular location on the chromosome and passed on to offspring

The gene as the fundamental unit of heredity is the original meaning of the word as first geneticists intended it. This essentially explains the reason why, during last century, a burst of research occurred in the genetic field: it was carried out in order to discover the genes responsible for the most various traits, from the ones causing diseases to the ones responsible for genetic variation across populations. In fact, the scientific community was convinced that genes retained all the crucial information necessary for organisms’ generation, growth, survival and reproduction (Sarkar, 1998).
