Dna

DNA DNA, or Deoxyribonucleic Acid, is described, in Encarta Encyclopedia as a genetic material of all cellular organisms and most viruses. DNA carries the information needed to direct protein synthesis and replication. Protein synthesis is the production of the proteins needed by the cell or virus for its activities and development. Replication is the process by which DNA copies itself for each descendant cell or virus, passing on the information needed for protein synthesis. In most cellular...

DNA and RNA

 Roles of DNA and RNA in the Human Body and Medicine Anatomy and Physiology 1 Dr. Joy Henry Schonathan Crews 3/20/2015 Roles of DNA and RNA in the Human Body and Medicine Introduction Deoxyribonucleic acid (DNA) is the foreman of the body with a strict set of blueprints for what needs to be done in an organism’s cell and how.1 Each cell is encoded with a specific sequence of DNA which stores how it is to be made and reproduce. Ribonucleic acid (RNA) is the assistant to...

DNA Extraction

Report August 28, 2013 DNA Extraction on Onion (Allium cepa) and Human Cheek Cell Arriza, Rolland Merch Buscato, Carl G. Butil, Conrad G. Leonida, Renee Theresa ABSTRACT This activity observes the DNA present in onion (Allium cepa) and human cheek cells by extracting it with the addition of lysis buffer and chilled ethanol. The lysis buffer is prepared from squeezed onion mixed with salt and Pantene Pro-V Shampoo. The buffer degrades the protein enveloping the DNA found in onion and cheek...

Dna and Rna

General Biology DNA and RNA Deoxyribonucleic Acid and Ribonucleic Acid • DNA is deoxyribonucleic acid. It is located in the nuclei of cells, which make up the body. Consequently, DNA can be considered as one of the building blocks of the body. Where is DNA found? DNA, or deoxyribonucleic acid, is the hereditary material that lies within the nucleus of all cells in humans and other living organisms. Most of the DNA is placed within the nucleus and is called nuclear DNA. However,...

Structure of Dna

chromosomes are very long compact coils of DNA (Deoxyribonucleic Acid) that store all the information that the body inbeds such as how one looks and functions. This paper will first describe the structure of DNA; second discuss how the structure of DNA allows it to serve as the basis for inheritance, third examine how meiosis allows DNA to be divided into gametes and finally, describe how this relates to Gregor Mendel’s patterns of inheritance. The structure of DNA DNA is a thread formed by two strands...

Dna Profiling

Legal Studies Essay DNA Profiling Breakthroughs in DNA testing have brought success to what would have otherwise been unsolved cases. DNA profiling is a technique used by many scientists and police to match DNA samples found at the scene of a crime with their respective counterparts generally found on their database. DNA profiling has helped match blood and semen samples found at the scene of a crime to the perpetrator, managing to sometimes solve cold cases that have been closed for decades...

Dna Extraction

Objective : To extract the DNA from onion samples. Introduction : Nuclues has DNA molecule in it. It is packaged into thread like structure known as chromosomes. Each and every chromosome is made up of DNA tightly coiled many times around proteins which is known as histones. Histones supports the structure. Chromosome cannot be visible even under the microscope if the cells are not dividing. DNA consist of 2 long polynucleotide which is composed of 4 types of nucleotide units. Nucleotides...

Dna Lab

The investigation on the average mass of DNA with the mass of banana, strawberry and kiwi. Purpose: The purpose of this lab is to investigate the comparison between the amount of DNA per gram of fruit that can be extracted from a banana, strawberry and kiwi and to determine which one has more DNA. Hypothesis: The banana genome contains 837 MBPs and the strawberry genome contains 206 MBPs and the kiwi genome contains 128 MBPs. This states that there are more base pairs in a banana genome...

Dna Extraction

Introduction DNA (Deoxyribose Nucleic Acid) is a nucleic acid that has many names, each representing the phases that it undergoes (chromosomes, chromatin, genes/alleles); it resides in the nucleus (bound by 2 *phospholipid bilayers) of almost every cell in the body (red blood cells being an exception). DNA (your genotype) is double stranded and is responsible for replicating (from 46 to 92) during Interphase, so that mitosis can make new cells, repairing and allowing for growth in the body. It is...
