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.

- NASA sends a mission to Mars that brings back a new life form! It is carbon-based and its genetic material is similar to Earth DNA except that it uses 6 different nucleotide bases instead of 4. Its proteins are also similar to those on Earth, but there are 60 different amino acids instead of 20. In order to study this new life form further, the National Science Foundation asks you for your ideas about the genetic code for this organism. How many spaces would you propose are in each codon of the genetic code for this new organism? Why?arrow_forwardAll life shares DNA as the hereditary material. From an evolutionary perspective, why do you think this is the case?arrow_forwardThe fact that we find histones in Eukarya and Archaea is most likely to indicate indicate what? O A. 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_forward
- An 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_forwardEVOLUTION 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_forwardGenetically speaking, prokaryotes are different from eukaryotes because: a. prokaryotes usually have one main circular chromosome, whereas eukaryotes have multiple linear chromosomes prokaryotes do not usually have histone proteins to package their DNA prokaryotes do not have a nucleus to house their DNA as eukaryotes do prokaryotes have less total DNA than do eukaryotes All of the abovearrow_forward
- Researchers have reported advances in their attempts to synthesize life from scratch in a test-tube—bringing non-living matter to life. In the lab, they have been able to produce ‘protocells’ from fatty molecules that can spontaneously trap pieces of nucleic acids that possess the code for replication and metabolism. With continued progress, protocells may be synthesized that form self-replicating, evolving system that satisfy the conditions of life. Consider the scientific understanding that may be generated from this project. What scientific questions might the knowledge generated from this project help answer? Reflect on the broader significance of this work. What objections might be raised about this line of research?arrow_forwardMany animals have the p53 gene that makes a protein that regulates the cell cycle and helps prevent the formation of cancer cells. The table below shows the percentage of p53 gene sequences that the 4 species have when compared to humans.
