Question
Chapter 17, Problem 11TYK
Summary Introduction
To explain:
The reason for the existence of bacterial cells that can grow on a media without requiring threonine, leucine, or biotin and yet requiring methionine.
Introduction:
Lederberg and Tatum experimentally proved that a transformation occurs in the bacterial genome. They did so by placing bacterial cells that require different nutrients to survive on minimal media (media lacking essential nutrients). Some of the colonies from these mixtures, when placed on minimal media, were able to grow without any addition of nutrients. By this experiment, they concluded that genetic recombination had taken place that created new gene combinations capable of synthesizing all nutrients.

Materials
In order to determine the genetic material of a T2 phage, Alfred Hershey and
Martha Chase conducted experiments using T2 phages that infected bacteria. In
one treatment, they grew phages with radioactive sulfur. In another treatment,
they grew phages with radioactive phosphorous. They allowed both types of
phages to infect bacterial cells. After infection, they found that only bacteria
infected with phages grown with radioactive phosphorous showed any
radioactivity. Why did they use radioactive sulfur and phosphorous for this

for the P53 Gene, pick an exon and design two set of primers for a region that is at most 600 bp. Briefly explain why one of them is better than the other. You do not need to include every thermodynamic calculation or figures, just create a table like the one PrimerBLAST provides (you can use it directly).
E. How many nucleotides would be required to generate a polypeptide that is 15
amino acids long? This requires knowing how many nucleotides of DNA code for
one amino acid.
F. Assuming that there are between 20,000-25,000 genes in the human genome, do
you think there are 1) fewer, 2) approximately the same number, or 3) more
proteins in the human genome? Explain your answer.

- You are a molecular biologist studying a defective human protein that is known to be the cause of a rare cancer. You isolate the suspected protein from a person with this cancer and compare it to the same protein in a person without the cancer. You discover that the protein isolated from the cancer patient is slightly smaller in size when compared to the protein from the unaffected patient. Furthermore, you discover that the protein from the cancer patient differs in almost every amino acid starting after the twenty-third amino acid. What is the likely explanation?arrow_forwardDiscuss the following statement: “from the nucleotide sequence of a cDNA clone, the complete amino acid sequence of a protein can be deduced by applying the genetic code. thus, protein biochemistry has become superfluous because there is nothing more that can be learned by studying the protein.”arrow_forwardBiochemistry: Site-directed mutagenesis, in which individual amino acid residues are replaced with others, is a powerful method to study enzyme mechanisms. In experiments with particular enzyme, various lysine residues were replaced with aspartate, yielding the results summarized in the table below: Enzyme Form: Enzyme Activity (U/mg) Native enzyme: 1,000 U/mg Recombinant Lys 21 to Asp 21: 970 U/mg Recombinant Lys 86 to Asp 86: 100 U/mg Recombinant Lys 101 to Asp 101: 970 U/mg a. What might be inferred about the role of Lys 21, 86, and 101 in the catalytic mechanism of this enzyme? b. Discuss where within the enzyme one might find Lys 21 and 101. Are these residues likely to be evolutionary conserved in this enzyme? Explain c. Is Lys position 86 likely to be evolutionary conserved? Explainarrow_forward
- As part of a project investigating potential new drug targets in the fight against malaria, you are seeking to clone the gene for a protein from the malaria parasite Plasmodium falciparum. You wish to express this protein in BL21 (DE3) cells, a standard laboratory strain of Escherichia coli. After purification of your protein, you run an SDS-PAGE gel and notice that the major band has lower molecular weight than expected, so you fear you are getting a truncated version. 1. What technique could you use to confirm that you are obtaining a shortened version of your intended protein? explainarrow_forwardAs part of a project investigating potential new drug targets in the fight against malaria, you are seeking to clone the gene for a protein from the malaria parasite Plasmodium falciparum.

- A chain of biochemical events is responsible for Aequorea victoria turning green. Firstly, the protein aequorin converts chemical energy into blue light. A second protein, known as GFP (green fluorescent protein), absorbs the light. Aequorin is a 21 kDa protein with a pI of 4.5 that generates blue light from an attached non-protein chromophore. GFP is a 27 kDa protein with a pI of 6.2. In order for it to fluoresce, 3 amino acids undergo a remarkable reaction when they are folded in the right way. Aequorin does not absorb light in the visible range, and GFP absorbs light at 395 nm and 475 nm. 1. Sketch what you would see if you ran a mixture of aequorin and GFP over a size-exclusion column. In your sketch, include absorbance data at 280, 395, and 475 nm.arrow_forwardYou are studying a bacterial metabolic pathway that results in the synthesis of a product, vitalin, that is essential for survival.

- In the transformation experiment by Griffith, two strains of an organism was injected into a mouse model. One, he labelled S was a heat-killed but pathogenic strain while the other, R was a non- virulent or non-pathogenic strain. Within 48 hours, the mouse died and only the S strain was obtained from the dead mouse. What conclusions can you derived from this experiment? A. Some of the pathogenic S strains survived, proliferated and subsequently overpowered the R strain. B. The R strains mutated and were converted to a pathogenic S strain. C. The R strains assimilated the DNA from the S strain and were transformed into the S strain. D. The R strain DNA hybridized with the S strain DNA such that the daughter DNA of the new generation of R all contained the S DNA. E. All of these conclusions are possible.arrow_forwardGiven: eukaryotic cells can make different proteins, using only one gene.
