Scientists at University of Texas created First Living Organism With 'Artificial' DNA. So, B is eliminated. (Because we are required to find wrong option, whereas B is right.) - DNA replication can also be performed in vitro (outside a cell). So, C is eliminated. - Cell division of Chlamydomonas is usually achieved in the laboratory by alternation of light and dark periods. So, D is eliminated. Thus we are left with answer A.
