A given organism has a gene A that produces a protein, cellular albumen, which traps water within cells. This organism lives is a cool, wet environment, and hence traps too much water in its cells. This organism thus has a reduced chance of both surviving and reproducing. When the organism dies -- and it dies owing to the effects of this gene -- this gene is eliminated from the gene pool. This is specifically an example of (pick the one best answer): A. genetic drift B. environmental selection sexual selection C. gene flow D. disruptive selection mutation

The G-value paradox states that the number of protein-coding genes is correlated with organismal complexity. Group of answer choices True False     Next

The Escherichia coli bacteria produces an enzyme that can inactivate ẞ-lactam antibiotics. By contrast, the Salmonella enterica bacteria is killed by ẞ-lactam antibiotics. When a community contains both types of bacteria, fewer of the Salmonella enterica bacteria are killed. This is an example of Exposure protection Gene Mutation Protection mediated by interspecies communication Vulnerability due to cross feeding

The protein Menchie is conserved from cats to humans. The region upstream of the menchie gene has three conserved sequences: region A, B, and C. Mutations were made in this upstream region by removing these regions or changing the orientation of these regions. Additionally, the coding sequence for Menchie was replaced with the coding sequence for green fluorescent protein (GFP; gene = gfp). GFP fluorescence was measured for each of the indicated constructs and the results are summarized. The arrow indicates the direction of transcription and where transcription starts (the +1 site). c. Which region (A, B, or C) contains an enhancer sequence? Briefly explain your answer, using at least two lines of evidence from the results shown; please use the #s to indicate the line of evidence you are describing. d. Which region (A, B, or C) contains a silencer sequence? Briefly explain your answer, using at least two lines of evidence from the results shown; please use the #s to indicate the line…

How can you use this piece of information to help you explain to your friends what is the significance of mutations in the emergence of new genetic properties (alleles) that may result (or not) in new phenotypic characteristics? (Recall that not all SNPs affect phenotype.)
