Textbook Question
Chapter 1, Problem 12TYU
EVOLUTION CONNECTION A typical prokaryotic cell has about 3,000 genes in its DNA, while a human cell has almost 21,000 genes. About 1,000 of these genes are present in both types of cells. Based on your understanding of evolution, explain how such different organisms could have this same subset of 1,000 genes. What sorts of functions might these shared genes have?

The Selfish Gene is a radical theory that argues that all living creatures are essentially vehicles for their genes- hence, we all are a “survival machine" for our genes.
In the light of what you have learned about the molecular structure and function of the gene, is this perspective still relevant? Cite specific biological phenomena to prove your point.
Evolution in Humans
1) explain how differences in gene expression of genetically similar organism can result in
different evolutionary outcomes
2) describe the evolution of symbolic thought in humans

Give trivia about this species. Does this organism produce oxygen? Explain. What are the ancestral species of your chosen organism? Has this species been genetically engineered? If yes, in what way? How does this species reproduce? What organisms have similar structures to this species? Do these structures have the same function? Does the species have tissues, organs, and/or organ systems?

Histones evolved prior to Archaea and Eukarya branching off from Bacteria B. Histones evolved after Archaea and Eukarya branched off from Bacteria • C. Histones are found only in multicellular organisms • D. Histones are necessary to protect DNA from nucleases O E. Histones are a product of convergent evolutionarrow_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_forward
- Just as all life shares a last universal common ancestor, all eukaryotes share a last eukaryotic common ancestor (LECA). In considering what LECA was like, scientists look for features and processes common to all or nearly all eukaryotic groups. They assume that these structures emerged before the groups diverged and thus were present in LECA. Make a list of the features and processes that you think might have been passed down from LECA to modern eukaryotes.arrow_forwardAn astrobiologist discovers a new form of life on another planet. Life here appears to have evolved using DNA as the information storage molecule and proteins to carry out cellular function, much like on Earth, however the individual building blocks on this planet are different. On this planet, there appear to be 3 different nucleotides in the DNA and 30 different amino acids in the proteins. Which of the following conclusions about this form of life would be most justified? These organisms can produce proteins no more than 30 amino acids in length. These organisms must produce 30 different forms of mRNA Amino acids must be coded by sets of 3 nucleotides in the DNA of the organisms on this planet. Amino acids must be coded by sets of at least 4 nucleotides in the DNA of the organisms on this planet. These organisms cannot produce more than 30 kinds of protein.arrow_forwardBased on genes from mitochordrial DNA the most accepted tree of life includes three domains.

- 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_forwardWhat is Le Chatelier's Principle? Describe how this principle explains the reversal over evolutionary time of a cellular process of your choice. In the course of this explanation, use two sketches to completely describe how the cellular process ran before and after it was reversed by Le Chatelier’s principle, including 1. all inputs/where they come from 2. all outputs/where they go 3. what good the process does the cell.arrow_forwardOne of the simplest definitions of a life-form is anything with the capacity to reproduce and regulate itself. Before life began, the complex organic, or hydrocarbon-bearing, molecules that makeup RNA and DNA, the building blocks of life, must have formed. No one knows exactly how life is formed from these molecules, but many ideas have been put forward. As you enter this area, go toward the large video screen on the right and explore the “Life at the hydrothermal Vents” label deck. Some scientists theorize that life begins at deep-sea vents. Find three lines of evidence to support this claim.arrow_forward
- Explain why the answer is correct. 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_forwardDo question number 3 making inferencesarrow_forwardYou are 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?
