How do prokaryotic genomes compare to the genomes found in eukaryotic organelles? Why?arrow_forwardWhat are some reasons why, in multicellular eukaryotes, genome size is not necessarily related to number of protein-coding genes or organismal complexity?arrow_forward
- What is the evolutionary advantage of genomes?arrow_forwardExplain the likely evolutionary origin of mitochondrial and chloroplast genomes. How have the sizes of the mitochondrial and chloroplast genomes changed since their origin? How has thisoccurred?arrow_forwardThe Japanese canopy plant (Paris japonica) has one of the largest of all eukaryotic genomes, with approximately 150 billion base pairs, about 50 times the size of the human genome. In contrast, the bladderwort Utricularia gibba has one of the smallest plant genomes, with only 82 million base pairs. What predictions can you make about the genomes of these two species?arrow_forward

- how can genomes with a relatively small number of genes produce the vast complexity of phenotypes that results in living organisms, including humans?arrow_forwardIn 1995, Hamilton Smith, Craig Venter and co-workers published the first complete genome sequence of a self-sustaining organism, that of the bacterium Haemophilus influenzae. Analysis of the genome sequence revealed that the organism does not have a gene that could encode a telomerase enzyme. What is the potential evolutionary consequence of this? Explain your answer.arrow_forwardAntibiotics such as chloramphenicol, tetracycline, and erythromycin inhibit protein synthesis in bacteria, but have no effect on the synthesis of proteins encoded by eukaryotic nuclear genes. Cycloheximide inhibits the synthesis of proteins encoded by nuclear genes, but has no effect on bacterial protein synthesis. How might these compounds be used to determine which proteins are encoded by mitochondrial and chloroplast genomes?arrow_forward
