Question

Quizplus · Accepted Answer

Proteins perform the majority of the work within cells, including enzyme catalysis, cell signaling, and structural support. Zygotes are only found in sexual reproduction and have no role in the daily work of a cell. Genotypes refer to an organism's genetic makeup and do not directly perform work within cells. DNA contains genetic information, but it is not directly involved in the daily functions of a cell either.
