Over the years research has revealed that the use of DNA (deoxyribonucleic acid) and proteins can be monitored through the progress of evolution. This monitoring can be achieved by the use of evolutionary tape measures. In order to get a better understanding of how this process will work the team will take a look at the main concepts of this process. The team will also delve into the importance of each concept and how these concepts can be applied in an industry. The team will also discuss these concepts and how they affect real-life by providing examples and the important role these concepts play. Finally the team will look at the relationship of the real-life examples and compare them against other biological concepts.Main Concepts to DNA and Proteins as Evolutionary Tape MeasuresDNA and proteins document the hereditary background of an organism (Campbell, et al, 2007). Since the DNA molecules are passed from parent to offspring they can be used to help determine the sequence of proteins in the offspring. This same sequence can be extended to develop the molecular genealogy between species (Campbell, et al, 2007).Two main functions are provided by the DNA of an organism. The first function allows for growth and development of the organism by providing protein synthesis. The second function is to replicate itself and provide offspring with copies which gives all descendants its own protein-synthesizing information.Importance of Each Concept and How the Concepts are Applied to an IndustryThe concepts mentioned above are important when trying to understand how organisms have evolved. By deciphering the role of DNA and proteins, geneticists can get a better understanding of how organisms have changed over time and have adjusted to changes in their environments. By using genetic research scientists are also able to predict the probability of specific characteristics of offspring from parents as well as potential risk for mutations in genes that may be passed on to the offspring. This research has been extremely important in numerous industries.For instance, in the medical field, a large number of tests use DNA and proteins to identify lineage as well as disease. A simple swab from the inside of the check can determine the relationship between a parent and child or even between siblings. These multiple tests, although relatively new, have become common place in society and are used on a daily basis as diagnostic tools or as a way to take preventive steps to avoid serious illnesses such as cancer (Noveck, 2008).Although the medical field has an obvious use for DNA and protein research, agriculture also uses these concepts. By using these concepts scientists are able to identify the genes in plants that are responsible for certain characteristics. Once these genes are identified scientists are able to alter them genetically to create new species or even change existing species. One reason for re-engineering an existing species would for environmental...

660 words - 3 pages containing DNA are collected and purified, The cells are broken open and their DNA is separated, if only a small amount of DNA is available it may be duplicated by a process called amplification. The DNA is treated with proteins (called restriction enzymes) that cut it at specific locations to provide DNA fragments of different lengths, since each persons DNA sequence is unique the pattern of DNA varies among every individual. Using an electrical

DNA Lab Essay

548 words - 2 pages Bio 181Lap report#12DNA is a hereditary double helix strands that present in the nucleus of living cells. DNA acts as the blueprint for all of the proteins synthesized by that cell. There are many chromosomal regions that vary widely between individuals called polymorphic DNA (poly="many", morph="form"). These regions may or may not encode proteins. By examining several of these polymorphic regions within a person's DNA, a DNA "fingerprint" is

The Importance of Deoxy-ribo Nucleic Acid

986 words - 4 pages 80% of a human's DNA. DNA provides the map of the proteins and genes we express in each individual, and without it, we would be a totally different person. Besides DNA, nucleic acids also perform other functions in our body, but the role it plays in the formation of DNA is the most important. Let's break down what DNA really is. DNA stands for Deoxy-ribo Nucleic Acid. Deoxy means that there is a missing oxygen atom in the sugar on the second

All of those characteristics, nature, and distinctiveness of the proteins give each organism a unique indiuvality. The DNA sequences carried in each cell in blueprint. They are the instructions that tell the cell how to be part of an animal, plant, fungus or bacterium. The majority of genes are instructions that tell cells how to make proteins. Proteins are the active elements of

DNA: One of the Biological Macromolecules that Contain Knots

1023 words - 5 pages Summary In the article “One- pot pentaknot,” published by Advance Online Publishers and submitted to the Nature Chemistry Journal in November, 2011, Ayme Et. Al., (2011) describes DNA as one of the biological macromolecules that contain knots. The report states that knots are also found in proteins and are important structural components of deoxyribonucleic acids. Similarly, the report, “New Motifs in DNA nanotechnology” by Seeman et al, (1998

1470 words - 6 pages Detailed description of DNA replication and RNA transcription, AP level.DNA ReplicationThe purpose of DNA replication is to make sure the daughter cell in cell division has its complete set of DNA, which occurs during the S phase of the cell cycle. To for a cell to function, it must have DNA (exact DNA from parent cell), for DNA determines the sequence of nucleotides in mRNA, which in turn determines the sequence of amino acids in proteins

Solving the Structure of DNA

945 words - 4 pages structure of DNA. Throughout the book, Watson and Crick were always against Pauling. There was a rivalry between these two groups. Pauling was known for solving the structure of proteins and coming up with the α- helix (35-36). Pauling was the first one to come up with a structure of DNA(156). Pauling came up with “a three-chain helix with sugar-phosphate backbone in the center” (159). Watson was able to deduce that Pauling’s structure would fall apart

Second is the secondary structure, which is some basic common shapes that are found within a protein. The alpha helix and beta sheet are the two main examples of this. There can be many of both of these within a protein. Tertiary structure can’t be described as a single shape, it is basically a glob. Tertiary
