Dna From The Nucleic Acid Structure

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 for short, is a substance in all living organism that duplicates itself. It is the carrier of all genetic information, such as eye color, hair color, height, etc. DNA is found in all living things including both eukaryotic and prokaryotic organisms. DNA is tightly packaged in the chromosomes to start DNA replication. During this process, DNA unwinds so that it can be duplicated. DNA can be extracted from strawberries which can also explain how DNA can be used for medicinal purposes as well as explaining how DNA extraction originated.

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.

Biological sex is determined by chromosomes in your genes. At prenatal development, only a few weeks after conception, there is no notable difference between male and female structure until the Gonadal Ridges, the structure which develops either female or male sex organs, grows to determine the sex of the baby. All prenatal babies have genitalia that appears distinctly feminine until at three months, hormones- testosterone if the baby’s to be a boy, and oestrogen if the baby’s to be a girl- is released and the baby develops into the hormone determined gender. For these reasons it is believed that there is a direct link between chromosomes and sex, and therefore sex and

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

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

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 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.

All the methods you hear about the prediction of baby’s sex before birth are silly old wives’ tales. In fact, researches confirms that it is only a folklore about telling baby’s sex because it depends on the chromosomes. “If your belly hangs low, you are having a boy, If its high, then you are having a girl; It is pure myth because the position of the baby is due to tone of the muscle”.

The purpose of the introductory activity was to analyze the pH of a mixture of a strong base and weak acid. The purpose of the guided-inquiry lab was to analyze the concentration of sodium carbonate by titrating the substance using a nitic acid solution. Introductory Activity 5 mL of both 0.2 M ammonia and 0.1 M acetic acid were placed in separate test tubes and their pH was determined with pH paper. A mixture was created by pouring both together and its final pH was recorded. The strength of the acid and base was determined and whether the two had equal concentration.

Roles in gender has to be determined before we are even born. Once a child’s sex is revealed, he or she will be placed into certain roles. Before we are even determined to be a male or female, we received 23 chromosomes from each parent. Of the 46 chromosomes, 45 are unisex. It is not determined until the six week which chromosome takes over and determines the sex of the child. As children get older, it becomes noticeable the differences that occur. It has been shown that women will mature quicker than men. A woman will develop their puberty about two years before a man. Also, they will live about five years longer than a male.

DNA stands for deoxyribonucleic acid. DNA is the set of nongenetic traits, qualities, or features that characterize a person or other living thing. Extracting DNA helps understand different types of genes, as there are 500 different types of genes in total and counting. DNA can be found everywhere. In every cell, in every

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

DNA started way back in 1868 by a physician named Friedrich Miescher. For a long time, the connection between nucleic acid and genes was not known, but in 1944 the American scientist Oswald Avery was able to prove that genes were made up of nucleic acid. The first person to find out about the structure of DNA or (deoxyribonucleic acid) truely was a women. Her name was Rosalind Franklin, she found the structure of DNA. But her work were stolen by two men, they go by Francis Crick and James Watson (Lloyd,2010). They soon got a Nobel Prize for their work.
