The definition of transformation is:
A.the shift of genetic information from DNA to protein.
B.the recombination of DNA strands during meiosis
C.the uptake of genetic information by a cell from the environment.
D.the combining of DNA during fertilization.
E.the changes caused by an organism evolving
The definition of transformation is C. the uptake of genetic information by a cell from the environment.
To determine the correct answer, we can break down the options and eliminate ones that are not relevant to the concept of transformation:
A. The shift of genetic information from DNA to protein: This refers to the process of transcription and translation, which occurs after the process of transformation. Therefore, it is not the definition of transformation itself.
B. The recombination of DNA strands during meiosis: This refers to the process of genetic recombination that occurs during the formation of gametes. Although it involves the rearrangement of genetic material, it is not specifically related to the uptake of genetic information by a cell from the environment.
C. The uptake of genetic information by a cell from the environment: This is the correct definition of transformation. It occurs when a cell takes up external genetic material, usually in the form of DNA, and incorporates it into its own genome.
D. The combining of DNA during fertilization: This refers to the process of sexual reproduction, where the genetic material from two parents combines to form a new offspring. It is not directly related to the process of transformation.
E. The changes caused by an organism evolving: Evolution refers to the gradual change in the inheritable characteristics of a population over successive generations. While transformation can contribute to genetic variation and potentially drive evolution, this option is too broad and does not specifically define transformation.
Therefore, the correct definition of transformation is C. the uptake of genetic information by a cell from the environment.
