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

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.
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.
References:
If all living organisms have the same pattern, then humans would have the same genetic code as a worm because all species have the same repeated pattern, DNA could not provide the variety needed for the genetic code.
Was the hypothesis supported? Be sure to explain your reasoning! (Sentence starters: “Yes, my hypothesis was supported. I know this because…” or “No, my hypothesis was not correct. It was proven to be false because…”)

- Describe the step-wise process of how inorganic matter on primitive Earth evolved into multicellular, eukaryotic cells. Be sure to provide enough detail with each step and make sure you cover inorganic, organic, protocells, prokaryotic, energetics, eukaryotic, and multi-cellularityarrow_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_forwardAll 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.arrow_forward

A) How the evolutionary transition from prokaryotic to eukaryotic cells through acquisiton of membrane bound organelles. B) How viruses first originated alongside cellular life through a hyper replicating RNA lineage. C) How individual replicating molecules like RNA, DNA, and proteins entered a molecular mutualism and became encapsulated forming protocells. D) How cycles of heat and electricity experimentally lead to the formation of amino acids in the lab.arrow_forwardEvolutionary microbiologists developed a theory about a common ancestor for all eukaryotic cells. Below is a model of the theorized changes during the origin of eukaryotic cells. Prokaryotes are not capable of phagocytosis, or engulfing outside particles by creating a pocket in the cell membrane. Which of the following changes in early prokaryotes could be predicted to result in the emergence of eukaryotic organisms? A - the development of genetic transfer mechanisms in prokaryotes B - the evolution of predatory or parasitic relationships in prokaryotes C - the emergence of collections of cells functioning together in prokaryotes D = the expansion of internal structures to support larger individual cells in prokaryotesarrow_forward

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_forward
