Chapter 1, Problem 10TYU
FOCUS ON INFORMATION
A typical prokaryotic cell has about 3,000 genes in its DNA while a human cell has almost 21,000 genes About 1000 of these genes are present in both types of cells. (a) Based on your understanding of evolution explain how such different organisms could have this same subset of 1,000 genes. (b) What sorts of functions might these shared genes have? Justify your choices

For eukaryote cells to evolve into new types of eukaryotic organisms, which of the following would one expect to occur? The correct answer is E a) these cells have evolved because they have different DNA because of mutations b) Their endoplasmic reticulum is synthesizing new and/or different proteins. c) These specialized cells activate new genes to synthesize new proteins. d) these organisms have new characteristics because they have acquired new genes. e) all of these are truearrow_forwardEvolution, which involves genetic changes in a population of organisms over time, is often described as the unifying theme in biology.

- EVOLUTION LINK DNA technology, such as the production of transgenic animals, is possible only because widely different organisms have essentially identical genetic systems (DNA RNA protein). What is the evolutionary significance of the universality of genetic systems in organisms as diverse as bacteria and pigs?arrow_forwardRecall from our classes on molecular evolution that some proteins evolve more rapidly than others. For example, the oxygen-carrying protein myoglobin evolves more quickly than the D1 protein of photosystem II. What explains this difference in the rate of protein evolution? A. Proteins like myoglobin have evolved more recently than proteins like D1 and thus have been forced to evolve more quickly. B. Changes to the sequence of some proteins can be tolerated as they don’t alter fitness; for other proteins, sequence changes are usually harmful. C. In constrained proteins like D1, evolution results primarily from nucleotide changes that alter the amino acid sequence of the protein. D. Protein evolution is dependent upon the rate of gene mutation and some genes have a higher rate of mutation than others.arrow_forward1.) I have attempted to make connections between these topics throughout the semester: the idea of multicellularity, complexity, pattern formation, signaling, embryonic development and postembryonic development. Discuss these ideas from simple organisms, like Dicty or Volvox to more complex organisms like insects and vertebrates. How are these ideas similar and how are they connected through evolution? Use examples from class. (20 Points, limit to 1 page) 2.) Early in this semester I introduced you to the concept of the developmental biology tool kit. Throughout the semester we have built upon that tool kit. A sample of your tool kit includes gene expression, morphogens, scaffolds, time, endocrine, nervous system, cell division, electromagnetic fields, migration, and cell adhesion. Using examples from embryology, regeneration and post embryonic development discuss the aforementioned tools. (20 Points, limit to 1 page) 3.)
