As we have discussed in class, individual phylogenetic methods are best suited to particular kinds of problems. For each of the following data sets, assess the suitability of maximum parsimony to that data set. Then do likewise for maximum likelihood. Clearly explain your reasoning in each case. (Note: some data sets may be suitable for both maximum parsimony and maximum likelihood, while other data sets may not be suitable for either method.) A researcher wants to reconstruct the evolutionary history of a 500-bp noncoding region. Her data consist of 15 DNA sequences representing a broad sample of eukaryotic organisms. A biomedical research group is studying the evolution of HIV (the virus that causes AIDS). Their data consist of 700 RNA sequences, each approximately 8 Mb long. In addition, the genomic region they are studying involves extensive recombination and transfer of genetic information from one strain to another. An ecologist wants to reconstruct the evolutionary history of the chytrid fungus currently infecting amphibian populations worldwide. His data consist of 10 samples from each of 50 populations, focusing on a 6-kb intron within a specific gene. Note that the chytrid epidemic is believed to have begun in the early to mid-1970s.
how can You characterize a new enzyme's kinetics. No, the activity does not change with increasing enzyme concentration correctly. The enzyme may be only active in a dimer that forms a high concentration.
Write down a detailed lab report on Separation and detection of proteins. Your report must include Title, Introduction, Materials and methods and three references for this report.
If the experimental animals in a chamber were engaged in physical activity, how would this change the results of metabolism experiment.
If the genes were expressed in the cell, predict that signal would win out for the following combinations. Give details your reasoning.
Discuss how medical technologies are evaluated. Give examples of at least two evaluation methods that have been discussed either in popular press or scholarly journals.
define the results of the three chi-squared analyses. what do these analyses tell you about the chromosomal arrangements and the genotypes of plants 1 and 2 and the events that occured during gamete production.
What are the benefits of genetic engineering versus the potential risks. Critics claimed that the experiment was inconclusive. Which of the criticisms would be addressed by using a swan-necked flask in its place of the unsealed flask.
Describe why organisms only reproduce their own kind, and why offspring more closely resemble their parents than unrelated individuals of the similar species.
Using the provided DNA code, derive the correct amino acid sequence. Describe the necessary steps to arrive at the amino acid sequence, and explain each in detail.be sure to list the mRNA sequence.
