In the newly engineered cell created by the researchers at the JCVI, what was derived from a previous cell, partially supporting one aspect of cell theory?

Cells can only derive from pre-existing cells.

Explanation:

The cell theory has three major postulates: 1-all organisms are composed of cells, 2-the cells are the basic unit of all living forms, and 3-the cells derive from pre-existing cells. In 2010, the J. Craig Venter Institute (JCVI) designed in the laboratory a synthetic bacterium that is able to auto replicate himself, and thereby supporting the third statement of the cell theory. This bacterium was named as Mycoplasma mycoides JCVI-syn1.0 and its creation represented a milestone in synthetic biology. M. mycoides is a bacterium that has only 473 genes coded by 531,000 bases pairs (bp), this being one of the smallest genomes of all living forms.
