It is based on the principle that fluorescence resonance energy transfer can be used to detect duplex formation between complementary nucleic acid strands.

The degree of complementarity between two nucleic acid strands may vary, from total complementarity to none.

She told them about viroids, nucleic acid strands with no protein coating, and how they cause stunting in plants.

Melting is the process by which the interactions between the strands of the double helix are broken, separating the two nucleic acid strands.

Nucleic acid strands realign when "normal" conditions are restored during annealing.

If the conditions are restored too quickly, the nucleic acid strands may realign imperfectly.

But the subunits of nucleic acid strands can be arranged in many different sequences, and a template strand can separate from its copy.

With prokaryote bacteria cells, the bacteriophage physically injects the nucleic acid strand into the host cell.

DNA nanostructures must be rationally designed so that the individual nucleic acid strands will assemble into the desired structures.

The last step is the primary structure design, which is the specification of the actual base sequences of each nucleic acid strand.
