brought technology to a level of very deep exploration about so many things that happens every day to us. From a large scale of things‚ down to the smallest and tiniest piece they explore all of these. One of these smallest things yet very interesting that we can sometimes never imagine of existing because we can’t see it through our naked eye that is bounded to all of us living things is the DNA. Every now and then‚ technology has been used in every aspect in our life. But we know that technology has

Module 2 Section 2 EXPERIMENT: DNA & Protein Synthesis Exercise 1 – Modeling DNA 1. List the four bases which are found in DNA. (1 pt) The four bases found in DNA are cytosine‚ adenine‚ guanine and thymine. 2. Fit any six nucleotides together to form a row‚ then list the six nucleotides in the order you used them. Work with your model pieces and try fitting the bases together to make a double strand as shown in Figure 9 of the lab manual. Which nucleotides form

Bio 1 Lab: Electrophoresis and DNA fingerprinting Jani Lynette Hagen October 31‚2014 U74644799 Electrophoresis is a technique which uses an electric field to separate molecules‚ allowing for identification and characterization of the molecules. It is commonly used to separate nucleic acids and protein molecules of various sizes. To prepare the gel for electrophoresis the amount of agrose needed must be calculated. For a 0.8 percent gel 0.8 grams of agrose is necessary per 100 ml of buffer. The DNA

extract DNA from a strawberry using limited household items. This was accomplished with the prior knowledge that the DNA is stored in the nucleus of the cell‚ and that is an extraction buffer would be needed to acquire the DNA. This experiment had no control group‚ however‚ if there was a control group it might be a group with no extraction buffer. The independent variable in this experiment is the extraction buffer. The dependent variable in this experiment is the ability to extract DNA. The constants

DNA extraction and purification is an essential tool in understanding the biological basis and significance of a eukaryotic cell. Its role is pivotal to numerous scientific applications ranging from basic science research to applied research. Hence‚ DNA is found in all living organisms. Fragaria x ananassa‚ also known as a strawberry has been widely used as one of the many biological models in studying DNA structures due to its accessibility. Strawberries are octoploid which contain large genomes

Radioisotopic labels would be used in experiments to identify semi-conservative replication in prokaryotes. Because we anticipated that a labeled DNA would have different density with unlabeled‚ which means‚ by analyzing the different density of DNAs‚ we can determine which of DNA is labeled‚ half-labeled or unlabeled. To this end‚ I will use c13 label the bacteria and abruptly change carbon source with C12. Then I will collect four samples in different time and analyze the results from centrifugal

Recombinant DNA Technology Recombinant DNA technology refers to the ability to isolate specific DNA sequences and alter or manipulate them to produce desired effects. More often‚ recombinant DNA technology is referred to as biotechnology. Recombinant DNA technology is fascinating in that it has developed into a multi-billion dollar industry‚ and completely revolutionized agriculture and pharmaceutical industries‚ all within the past 50 years. According to one account‚ biotechnology was born

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

The purpose of the DNA extraction lab was not only to inform students on how DNA is present in humans and all organisms‚ but to also educate them on how DNA can be extracted using common household materials. Also‚ the lab was very efficient as it introduced the students to extracting their own DNA found on their cheek cells as well as letting them take an observation on how DNA appears or how it is formed. Additionally‚ students were instructed through a very clear and simple procedure‚ which guided

Recombinant DNA Technology Benefits in Many Areas Recombinant DNA Technology is a DNA-based tool that allows scientists to find individual genes‚ cut them out‚ and insert them into the genome of another organism. Recombinant DNA Technology has been used to create different types of medicines for example human insulin. People with diabetes do not produce enough insulin for their own bodies‚ and in a lot of cases‚ they are allergic to non-human insulin. Due to the creation of Recombinant DNA Technology
