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, and genetic engineering involves manipulating cellular genetic material. Since genetic engineering techniques work across different organisms (showing unity of cellular life as per cell theory), it supports the cell theory. Options A (invalidates) is wrong. Engineering (genetic engineering here) is related to cell theory (as it manipulates cells' genetic material), so C is wrong. Both natural and artificial (genetic engineering) processes are relevant in biological studies, so D is wrong.

Answer:

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