Genetic engineering is applied to techniques like DNA cloning in which the steps are: step 1: DNA cutting from the parent source; step 2: DNA cut is pasted into the matrix to be modified; step 3: matrix is introduced to the host cell and step 4, vector DNA is isolated. Answer then is B.

The plant would stop photosynthesis due to the lack of light in the dim closet. Chlorophyll and other colors would be lost, and it would turn white. It would eventually exhaust the energy reserves in the roots and stem and perish.
<h3>What about photosynthesis?</h3>
Photosynthesis is the process through which plants turn carbon dioxide, water, and sunlight into oxygen and sugar-based energy. More than just the essential necessities of water and sunlight are needed for growth. The five key factors that influence how well your plants or crops develop are light, carbon dioxide, water, soil organisms, and nutrients.
Photosynthesis is primarily used to convert solar energy into chemical energy, which is then stored for use at a later time. This mechanism primarily provides energy to the planet's life systems. This indicates that without energy, it cannot happen (from the Sun). Chlorophyll, a green pigment found in leaves, absorbs the needed light. Chloroplasts, which contain chlorophyll, are present in the palisade and spongy mesophyll cells of plants.
