What was necessary for the gene aggregates to develop into cells?
The formation of enzymes
The aggregation of nucleotides and proteins
The presence of a nucleus
The ability to produce ATP
It was necessary for the gene aggregates to create enzymes before they could transform into anything resembling a cell. It takes enzymes to catalyse the different chemical processes that take place inside of cells. Conditions were now favourable for the development of the cell due to the steady synthesis of enzymes. The initial cell lacked a nucleus, was very basic, and resembled a bacterial cell. Therefore, the development of cells from gene aggregates required the presence of enzymes at every stage.
Option 1 is the correct answer.
