Question

which series lists the correct order of steps of binary fission from first to last?
sex pilus connects two cells plasmid dna is transferred complementary dna strands are created cells
separate
live cells bind to degraded cells dna is transported across the membrane dna is incorporated into recipients
dna
virus infects bacterial cell, new viruses are made dna is assembled in new virus new virus infects another
bacterial cell and transfers dna
dna is copied dna molecules attach to cell membrane cell membrane elongates and pinches off two
identical cells are produced

Explanation:

Binary fission is a form of asexual reproduction in prokaryotes. First, the DNA is copied. Then the DNA molecules attach to the cell membrane. Next, the cell membrane elongates and pinches off. Finally, two identical cells are produced. The first option describes conjugation (a form of horizontal gene transfer), the second describes transformation (uptake of extracellular DNA), and the third describes transduction (viral - mediated gene transfer).

Answer:

DNA is copied → DNA molecules attach to cell membrane → cell membrane elongates and pinches off → two identical cells are produced.
