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

increasingly complex task that requires active‚ continuing maintenance of digital media. This challenge has focused some interest on DNA as an attractive target for information storage because of its capacity for high-density information encoding‚ longevity under easily achieved conditions and proven track record as an information bearer. 1.2 Problem Statement: Previous DNA-based information storage approaches have encoded only trivial amounts of

Conclusion 3.2.1 1 Describe how the DNA code is translated into messenger RNA. DNA is translated into messenger RNA through transcription and translation. DNA is split through transcription and then it is translated to match into RNA. 2 How is the RNA molecule a “script” for the protein production process? RNA is a script for the protein production process because they set the RNA up to translate into a protein. 3 What is the function of hemoglobin in the body? Hemoglobin functions in the body by

Given the information that we now know about eyewitness testimony verses DNA science on page 440‚ this makes you stop and wonder about how many people have been wrongly imprisoned or put to death before DNA testing came along. From reading the article o page 440‚ it looks like the psychologists are using research to identify by showing individual pictures opposed to a police lineup; a person is most likely to choose an individual that may look close to the person that committed the crime.

Transformation of Bacterial Cells with Plasmid DNA Introduction: Transformation refers to the process in which the cell integrates foreign DNA to its genetic code‚ meaning it takes the genes and incorporates them into the cell’s current DNA. Cells that can do this naturally‚ most commonly bacteria and archea‚ are known as competent. The bacteria E. coli do not have high transformation competence under normal conditions‚ but can be manipulated to produce better results using

How many beads did you use? 87 beads There are multiple ways your cells can read a sequence of DNA and build slightly different proteins from the same strand. We will not go through the process here‚ but as an illustration of this “alternate splicing”‚ remove codons (beads) 52 - 66 from your sentence above. b. What does the sentence say now? (re-write

What is the function of non-coding DNA besides structural? There has been speculation about Non-coding’s function. Non-coding DNA has been said to be “Junk DNA” until scientists have found evidence for it having a structural function. More scientists are now trying to find more functions that Non-coding DNA might have. Non-coding DNA lies between genes on the Chromosome and does not code for amino acids. Regular DNA is also found in the Chromosome‚ but it does code for amino acids with help from

info in my DNA become my traits? This is a question that has been asked by many over the course of history.To answer this question we need to answer three essential questions‚ the first‚ how did we get our DNA‚ how did we go form one cell to trillions‚ and how did DNA become our traits. There is one essential driver to all of this‚ DNA‚ to understand DNA‚ we need to know what DNA is. DNA is two strands that contain genetic information in four bases‚ adenine‚ guanine‚ cytosine and thymine. DNA is located

experiment would be how the Restriction Endonucleases cleave the strands of DNA. For this experiment‚ pBR322 was the specimen to use. Restriction Endonucleases work by cleaving the sugar phosphate backbone of specific DNA sites. Restriction enzymes that have been isolated from bacteria have a defensive role. This idea is illustrated when an attacking foreign cell DNA is trying to alter the bacteria; restriction enzymes cleave the DNA rendering it inert. The second part of the experiment deals with Gel
