- Eric is studying the evolution of species. After performing DNA
analysis, he discovers a gene that is conserved from yeast to
humans.
- In which cellular processes is this gene most like to be involved?
-
- Could this gene have evolved to confer some of the complex traits that we observe in modern animals, like multicellularity? Briefly explain.
Homework Answers
The ERG28 gene was originally identified by microarray expression profiling as possibly involved in the Saccharomyces cerevisiae sterol pathway. Microarray analyses suggested that the transcription pattern of ERG28 closely followed that of genes involved in sterol synthesis. ERG28 was also found in Schizosaccharomyces pombe and Arabidopsis as well as humans, and in the latter was shown to be highly expressed in adult testis tissue.

1.Scientific progress requires that we clearly define the question we wish to answer. A clear, sharp definition of a scientific question is often the most difficult step in the process of discovery. Which of the following is the most accurate and complete description of the specific scientific question or problem we will address in this course? a. Humans have no individually unique properties; however, the specific combination of properties we have is not seen in other animals and these properties...

Lab 11: The Witte il An Introduction to Paleontology 1. Paleontology at the Witte: Paleontology is the study of fossils. Traditionally, multiple subdisciplines can be defined. For example, Paleobotany is the study of fossil plants, Paleodimatology is the study of ancient climates, and Palynology is the study of fossil pollen and spores. Paleontology differs from Archaeologyas the former includes the study of modern humans....

In what way is artificial selection different from natural selection? Question 1 options: A. There is no difference; both have caused evolution throughout the history of life on earth B. Artificial selection applies to changes in domestic animals only, while natural selection applies to all other species C. In artificial selection, human preference is the selecting force; in natural selection, environmental conditions are the selecting force. D. Artificial selection causes one species to change to another, while natural selection only modifies existing species. E. Artificial...
