What is the most accurate way to ex plain the relationship between antibiotic s and antibiotic-resistant bacteria?
a. Exposing bacteria to antibiotics causes DNA mutations that confer antibiotic resistance.
b. A population of bacteria evolves anti biotic resistance alleles in order to survive exposure to antibiotics.
c. Bacteria with alleles that confer antibiotic resistance are most likely to survive when exposed to antibiotics.
d. Antibiotics bind to alleles that confer antibiotic susceptibility, causing changes that make the gene pool more resistant.

- How does application of recombinant DNA influenced the way in today's life? Answer comprehensivelyarrow_forward(short answer) Imagine you’ve been offered a deal from a genomics company. You can get a free genome sequence – an analysis of all of your DNA that includes a report of your ancestry, traits and a medical profile. The medical profile tells you about diseases for which you have a low risk of getting, and also those you have a high risk of getting. Are you interested? Why or why not?arrow_forwardWhich claim is BEST supported by the evidence provided? A. The calf and the salamander have the most similar DNA sequences. B. The chick and the tortoise have the most similar DNA sequences. C. The fish and the chick have the most similar DNA sequences. D. The pig and the tortoise have the most similar DNA sequences.arrow_forward
- A. What is the wild progenitor of maize and where is it found? B. George Beadle concluded that this plant was the likely ancestor of maize (corn) even though the two plants appear very different. What evidence did Dr. Beadle collect that led to his conclusion? C. How long ago was maize domesticated and what evidence was utilized to determine this? D. Dr. Doebley and his team compared the DNA sequence of maize to that of a number of teosinte varieties from throughout Mexico. What did their analysis reveal?arrow_forwardShort Answer: What are environmental effects in genes?arrow_forwardHypothesize how the MITF (micropthalmia-associated trasnscription factor) gene might interact with other genes in the dog genome. What type of genes are most likely to show an interaction with the MITF gene? How might the interaction of these genes impact the phenotype of a dog?arrow_forward
