Chapter 1, Problem 9TYU
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?

One 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.
EVOLUTION LINK. In what ways does evolution depend on transfer of information? In what ways does transfer of information depend on evolution?
All living things are divided into three domains: bacteria, archaea, and eukarya. They have several traits that are specific to each domain or shared across the domains.
Based on this information, what traits would the last universal common ancestor (LUCA) be expected to have?
A. Nuclear envelope, introns in genes, and peptidoglycan in cell walls.
B. Histones associated with DNA, circular chromosome, and peptidoglycan in cell walls.
C. Unbranched hydrocarbons in membrane lipids, histones associated with DNA, and introns in genes.
D. Circular chromosome, unbranched hydrocarbons in membrane lipids, and one kind of RNA polymerase.

- 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_forward1) Evolution describes the change of the genetic makeup of __________ A)a population. B)an individual. C)a species.

Which of the following statements best explains this difference? Eukaryotic cells have less DNA than prokaryotic cells. . Prokaryotic organisms are typically multicellular while eukaryotic organisms are unicellular. Eukaryotic cells are more structurally complex than prokaryotic cells. Eukaryotic cells are smaller than prokaryotic cells. Other question:) Which of the following correctly describes how high levels of fatty acid structures contribute to the rigidity of the cell membrane? The cell membrane becomes more rigid as the amount of unsaturated fatty acids with a kinked structure increases.

- Fossil evidence indicates that prokaryotes have been around for about 3.5 billion years, whereas the origin of eukaryotes has been dated at only about 1.5 billion years ago. Suggest why, in spite of the lesser time for evolution, eukaryotes are much more diverse (have a much larger number of species) than prokaryotes.arrow_forwardprokaryotic cells be smaller than eukaryotic cells and still carry on all the functions of life how?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
- On an island with no large predators, some ducks are born with a mutation that gives them stubby little wings. These ducks can’t fly, but there’s really no need to fly since there are no predators. In fact, they have an advantage because they don’t have to eat as much to support those big wings like the other ducks. Over time, the flightless ducks reproduce better than the regular ducks, and eventually all the regular ducks die out. What characteristic of life is being demonstrated here? Group of answer choices development high complexity evolution requirement for resources irritabilityarrow_forwardExplain which eukaryotic organelle about genetically modified people in the future. What is the function of this organelle?arrow_forwardJust 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_forward
- The fossil record suggests that the first cells were prokaryotes; scientists believe that eukaryotic cells evolved from prokaryotic cells in a particular manner; this theory is called endosymbiotic theory. Explain,in your own words what is meant by the endosymbiotic theory How does the structure of mitochondria and chloroplasts support the endosymbiotic theory ? asap please.arrow_forwardThe 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. References:arrow_forwardScientists have discovered a new, unknown single-celled organism. They decide to compare the DNA sequence of the ubiquitin gene of the unknown organism with classified organisms. The ubiquitin gene is a gene found in some variation in all cells.
