Question

question 25
small circular molecules of dna in bacteria that are used in genetic engineering are
o centromeres
o telomeres
o nucleoid segments
o plasmids

Explanation:

Plasmids are small circular DNA molecules in bacteria. They can be used in genetic engineering as vectors to carry foreign DNA. Nucleoid segments refer to the main DNA region in bacteria (not the small circular ones). Telomeres are structures at the ends of eukaryotic chromosomes. Centromeres are regions in eukaryotic chromosomes for spindle - fiber attachment.

Answer:

Plasmids
