ecall the E. coli long-term evolution experiment. What is the evidence that supports the notion of “historical contingency”? A. All strains that evolved to be Cit+ were found to have changes to the exact same gene. B. Cit+ cells could import citrate under both low oxygen and high oxygen conditions. C. That after 30,000 generations the genotypes of all 12 lines were identical. D. Replay experiments only produced new Cit+ strains after 20,000 generations
Can viruses adapt by natural selection? A. No, because there isn't a genetic basis for inheritance between parent and offspring virus particles. B. No, because there isn't a way to distinguish more fit from less fit virus particles C. Yes but only via human (domestic/artificial) selection D. No they evolve by mutations. E. Yes, virus particles that are most successful successful in reproducing quickly and infecting other host cells are the best adapted.

Certain species of blind fish living in perpetual darkness in the ocean depths have evolved from ancestors that could see. Research indicates that the brain centers for vision in these fish is degenerating, whereas the brain centers controlling other senses are enlarging. What might be the MOST probable reason for the loss of vision in these fish? O A. exposure to mutagens that caused the loss of vision B. progressive selection of genetic variants in the population leading to blindness as an evolutionary adaptation C. infection by cave-dwelling microorganisms that has led to degeneration of the eyes O D. extreme high pressure at the ocean depths causing a deterioration of vision
The origin of genes that have new functions often involves the divergence of geneduplicates. Duplicates can arise via severalmechanisms.a. One mechanism of gene duplication is retrotransposition, the insertion into the genomeof DNA produced by reverse transcription ofa messenger RNA. These gene duplicates areoften dead on arrival: they are pseudogenesas soon as they are formed. Why are suchduplicates so often dead on arrival?b. A second mechanism of gene duplicationoccurs via unequal crossing over duringmeiosis. Gene duplicates formed this way arefunctional more often than when they arise byreverse transcription. Why is that?c. If a gene duplicate is initially functional, whatare its possible ultimate fates? Which is mostlikely, and why?

DNA content and ploidy in various cell types( sperm and somatic cells) are related b. DNA is found to be the only macromolecule in eukaryotes that has different subunits. c. Gene transfer is a direct evidence as it has been facilitated by recombinant DNA techniques. d. The correlation of the action and absorption spectra of ultraviolet light support the interpretation that DNA is a genetic material. e. DNA is shown to be present in ribosomes, matrix, and nucleus, where genetic function is performed. f. DNA is shown to be present in mitochondria, chloroplasts, and nucleus, where genetic function is performed.
