Essay on Deoxyribonucleic Acid or DNA: Defining Our Life

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

While studying eugenics, genetics plays a detrimental role in determining heredity. Genetics is the study and behavior of genes ("Genetics"). These genes are encoded pieces of information that comes from both parents, these genes are found on any of the 23 pairs chromosomes; these chromosomes that contain genes form the human genome. 22 chromosomes all contain the same genes although slight variations of alleles, alleles are alternate forms of genes, and the 23rd chromosome contains the information for the zygote's gender.

Genetics is the study of heredity genes, and traits. Like how our parents' traits and genes are passed down to us. Chromosomes are the huge chunk of genes that wrapped around the proteins. Humans are supposed to have the total of 46 chromosomes. Females have XX chromosomes and males have XY chromosomes. Chromosomes are passed down to offspring, as well as, genes. Also, Genes are strands of DNA; they are like the instructions manuals for our body. Genes are the one that code for the traits. Dominant and recessive traits are the two types of traits are that passed down to the offspring. Usually the offspring show the dominant traits since this trait is a lot stronger than recessive traits. There is a less chance that the offspring will show the recessive traits. Since the recessive traits can only appear if the dominant traits are absent.

Genetics can help answer questions about our traits and why we look different and advance in different ways from each other in the world. Chapter 1 explains the basics about how genes work, and the portrayal of DNA and RNA. Chapter 2 describes RNA more in detail and it consist of the explanation of the human genome. Specifically, Chapter 3 clarifies how evolution works and how it relates to genetic and medical research. Furthermore, Chapter 4 and 5 explains the knowledge researchers have about genes role in health and diseases, and how society is affected with the advances in medicine and science given approximate credit to these researchers.

Genes pertains to any living organism chemical make, which is passed from one generation to the next, and effect blood type, eye color, skin color, and other traits which help classify living organism. The study of Genes, or Genetics is considered a field of biology but is entwined with other sciences and studies. Certain fields of study focus on the genetic structure of living organisms and the effects that the environment have on genes, while at the same time, studying the effects of genes in an individual, and the effect on the environment caused by an individual.

A gene is a region of a nucleic acid that contains hereditary biological information. For all cells, the nucleic acid is double stranded DNA, and it provides information for synthesis of RNA, and into protein, which is then expressed as hereditary traits in human.

Genetics is the study of heredity, which is a biological process where certain traits are getting passed from parent to offspring or child (“What is Genetics”). All of our genetic DNA lies within the nucleus of all living cells in a persons body. The DNA found in the cells make the human genome. “There are about 20,000 genes located in one of the twenty three chromosomes found inside the nucleus (“What is

Genetic: pertaining to genes or any of their effects. A gene is the smallest physical piece of heredity. It determines what features we will pass on to our children as well as which ones we have gained from our biological parents.

Scientist in early 1950s James Watson a biologist from Indiana University and Francis Crick a physicist were working at lab to discover the structure of DNA. The primary technique for structural analysis of biological molecules is X-rays. The wave length of X-ray is about the same as the space between the atoms in crystal matters. We learn and know that genetic information was carried on chromosomes made up of DNA and protein. Maurice decided and taken the first x-ray picture of DNA that lead him to suggest the DNA structure might be a helix. Watson was able to rely on Wilkins' research. If he had not, he may have not been the one to discover the structure of DNA. The biggest thing I learned from my research is that scientists can’t make discoveries

DNA also known as deoxyribonucleic acid is a complex molecule that carries the genetic information in the cell, essential to build and maintain an organism.

Genetics is the study of heredity, which is the process of passing traits/ genes down.

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

Sixty-five years ago, the structure of DNA was unknown. In contrast to other sciences such as chemistry, which dates to around the time of the Egyptians, and physics, which came into vogue during the 1600s, molecular biology is truly a modern phenomenon. Until 1952, many biologists continued to believe that proteins carried genetic material. The next year, In 1953 James Watson and Francis Crick published their findings on the structure of DNA. Their proposition states that DNA consists of a double helix with alternating deoxyribose and phosphate molecules in the backbone.

James D. Watson and Francis Crick met in Cambridge in the fall of 1951. They became great partners and friend that took on a challenge to understand gene replication and protein synthesis. They first solved the structure of DNA, creating a DNA's double helical structure that is still preserved in the National Science Museum today in London. Their second challenge was to find the answer of protein synthesis; of how genetic materials are replicated, where it took place, and what contributes to the process of replication. After creating DNA's helix structure, Watson moved on to investigating RNA's structure; it was then he discovers all RNA was to exist either as a viral component or to be combined with protein in ribosomes, which lead to his curiosity in protein synthesis in the ribosomal location.

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).
