Debbie Lester Biology Lab 13 1. Arrange the following molecules from least to most specific with respect to the original nucleotide sequence: RNA, DNA, Amino Acid, Protein Protein, amino acid, RNA, DNA 2. Identify two structural differences between DNA and RNA. Two structural differences between DNA and RNA would be that RNA contains ribose while DNA is missing the hydroxyl group form its ribose. Also, RNA is created by transcription of a gene locate in the cells of DNA. DNA is doubled stranded whereas RNA is single stranded. 3. Suppose you are performing an experiment in which you must use heat to denature a double helix and create two single stranded pieces. Based on what you know about nucleotide bonding, do you think†¦show more content†¦We will not go through the process here, but as an illustration of this â€Å"alternate splicing†, remove codons (beads) 52 - 66 from your sentence above. b. What does the sentence say now? (re-write the entire sentence) Mutations are simply changes in the sequence of nucleotides. There are three ways this occurs: 1. Change a nucleotide(s) 2. Remove a nucleotide(s) 3. Add a nucleotide(s) 3. Using the sentence from exercise 1B: a. Change the 24th bead to a different color. What does the sentence say now (re-read the entire sentence)? Does the sentence still make sense? b. Replace the 24th bead and remove the 20th bead (remember what was there). What does the sentence say (re-read the entire sentence)? Does the sentence still make sense? If it doesn’t make sense as a sentence, are there any words that do? If so, what words still make sense? c. Replace the 20th bead and add one between bead numbers 50 and 51. What does the sentence say now? Does the sentence still make sense? d. In 3.a (above) you mutated one letter. What role do you think the redundancy of the genetic code plays in this type of change? e. Based on your observations, why do you suppose the mutations we made in 3.b and 3.c are called frame shift mutations? f. Which mutations do you suspect have the greatest consequence? Why?

There was also a neutral buffer in each of the chemical mixtures. The neutral buffer regulated the pH to around 7. We got a color palette and once we mixed each together, we observed and saw a change in the color of the substance. The darker and more brown the substance got, the more oxygen produced by the reaction. Our results showed that amount of oxygen produced increasedRead MoreMy Reaction to the Movie, Apollo 13 Essay719 Words   |  3 PagesApollo 13 This was the first time I have seen Apollo 13, despite the fact that I had heard so many great things about it. After having some time to think about it, I can honestly say I took a lot of things out of it. Each of the four astronauts singled out by the film, Lovell, Haise, Mattingly and Swigart, all responded the many challenges appropriately. Mattingly in particular had a special challenge that he was left behind by his fellow crew members because there was a chance that he could haveRead MoreBrief Commentary on the Movie Apollo 13582 Words   |  2 PagesHe doesn’t put pressure on them to be mean, but he does it because he needs them to work fast and efficient. I personally would want to buy into his ideas and solutions, because he did help resolve a lot of the problems that went on with the Apollo 13 mission. The issue they needed to solve that was similar to our project was when they had to come up with a solution to fix the oxygen leakage. They had to use the materials they knew the men in space had with them. We are doing a similar project byRead MoreInternet Of Things : A Brief Review1250 Words   |  5 Pages Figure 1 Three dimension of the Internet of Things [3] II. LITERATURE REVIEW The IoT concept is attributed to the Auto-ID Center which was founded in 1999 at Massachusetts Institute of Technology (MIT). [4] Now, there are seven academic research labs of some universities from different countries including USA, UK, Switzerland, China, Japan, Korea, and Australia.

But in this technique, retinal blood vessels are needed to be extracted initially which is a nontrivial task and requires long processing time. From [7], [12] the dependency between detection accuracy and processing time can be referred. In [13] OD detection is done as a part of the whole work and adaptive morphological filtering method is considered. Also in this work average computational cost is analyzed. But the work presented in this paper is the inspiration of the work [14] where a lineRead MoreBCH2333A Syllabus Winter 2015 1 1110 Words   |  5 Pageslectures is key to your success in the course!
