The small, circular loops of dna in prokaryotic cells that are separate from the main chromosome and may carry genes are called
a
plasmids.
b
cristae.
c
pili.
d
ribosomes.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
