Question

analyze how modern genetic engineering techniques challenge or support cell theory principles.
a. genetic engineering invalidates cell theory
b. these techniques demonstrate the fundamental unity of cellular life while allowing for manipulation
c. engineering has no relation to cell theory
d. only natural processes should be considered

Explanation:

Cell theory states that all living things are made of cells, cells are the basic unit of life, and cells come from pre - existing cells. Genetic engineering techniques involve manipulating the genetic material (DNA) of cells. Since all cells have DNA (a fundamental aspect of cellular life), genetic engineering techniques support the fundamental unity of cellular life as proposed by cell theory.

• Option A: Genetic engineering does not invalidate cell theory. It works within the framework of cellular life (as cells have DNA which is manipulated).
• Option C: Engineering (including genetic engineering) is related to cell theory as it manipulates components (DNA) within cells (which are the units of life according to cell theory).
• Option D: Genetic engineering techniques (which are human - made manipulations) are also considered in the context of cellular processes as they interact with cellular components (DNA).

Answer:

B. These techniques demonstrate the fundamental unity of cellular life while allowing for manipulation
