Imagine that you travel around the world and find two populations of fish that look very similar, but one one population lives in a cold climate and is very cold-resistant (produces an antifreeze protein), while the other population lives in warm climate and is not cold-resistant (and does not produce the antifreeze protein). Okay, let's try to figure out how we would decide what the difference between the two populations of fish is - why one is cold-resistant (and produces an antifreeze protein), and the other is not cold-resistant (and does not produce the antifreeze protein). Which of the below results from some experiments you did would lead you to conclude that the difference between the two fish evolved by phenotypic plasticity? Group of answer choices A-Embryos from fish that grew up in the warm climate were raised in the cold climate. They produced the antifreeze protein and were cold-resistant. B-A mutation in the cold-resistant fish was discovered that is not present in the warm- climate fish. When the mutation was introduced into warm-climate fish, they produced the antifreeze protein and were cold-resistant. C-Both D-Neither
Genetic Recombination
Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.
Microbial Genetics
Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.
