A DNA strand contains a complete representation of everything about our physiology. It also contains instructions on how to form our body by repeated divisions of a single cell. Each cell needs to know when it should‚ split into two‚ split into different kinds of cell for tissue differentiation. Cells also need to know when to stop growing because the body or organ is mature‚ and when it needs to replace tissue lost by injury. All of that is encoded into one molecule. So in other words the benefit

DNA‚ which stands for Deoxyribonucleic acid is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms. The main role of DNA molecules is the long-term storage of information. These nucleic acids consist of long chains if chemical units called nucleotides. Nucleic acids are information storage molecules that provide the directions for building proteins. Described by the DNA testing centre‚ Inc.‚ “DNA is found inside the chromosome

Comment on the extent to which each of the following contributed to a more democratic society in the American colonies: (a) the Great Awakening (b) immigration (c) the Zenger case.ton Russell With the help of these key events‚ the colonies of America slowly evolved to become a more liberal country which shaped and changed the American colonies to progressively become a democratic government. In the eighteenth century‚ the colonial society became increasingly more democratic due to the Great

Background on Genomic DNA Isolation and Purification Generally‚ all methods involve the disruption and lysis of cells. This is followed sometimes by the removal of RNA (by RNAses‚ salt or other methods). Choosing which method to use will depend on many selection factors including: DNA is isolated from proteins by several methods including digestion of proteins by the enzyme proteinase K. Proteins are removed subsequently by salting-out‚ organic extraction‚ or binding of the DNA to a solid-phase support

DNA testing has overthrown the way police collect evidence in a number of criminal cases‚ especially rape and murder and consequently had a large impact on many past cases. However there are many disadvantages to DNA testing‚ such as a challenge of accuracy‚ the costs of DNA testing and the possible misuse of DNA. The prospect of a national DNA database in Australia has been heavily criticised with complaints of invasion of privacy and stigma against those with terminal diseases. Deoxyribonucleic

The process by which DNA turns into polypeptides is a complicated and long. Two main steps in changing the DNA into a polypeptide are transcription and translation‚ with transcription coming first. The process first starts in the nucleus of the cell. The DNA begins to unfold with the help of a helicase. During the transcription phase of the change‚ strands of DNA begin to unwind and the complementary mRNA is made or transcribed. The way they do this is by using the common pairs of DNA triplet bases

History of DNA Technology During the early1960s‚ there was great progress being made in beginning to understand the structure of genes and the mechanisms of their replication‚ expression‚ and regulation in prokaryotes and the viruses that began to infect them (Berg 2010). However at the time it was still unknown as to whether or not these findings applied to eukaryotes. This is because the tools used at the time for exploring genetic properties were not fit for the task. By the spring of 1972‚ the
