________ are Small Circular Pieces of DNA Frequently Found in Bacteria

Question

________ are small circular pieces of DNA frequently found in bacteria.
A) Transposons
B) Insertion sequences
C) Plasmids
D) Bacteriophage
E) Centromeres

Accepted Answer

Plasmids are small circular DNA molecules that are separate from the chromosomal DNA in bacteria. They typically replicate independently and carry genetic information that can provide advantages to the bacteria, such as antibiotic resistance. Transposons and insertion sequences are also commonly found in bacteria and can move around the genome, but they are not typically circular like plasmids. Bacteriophages are viruses that infect bacteria and inject their genetic material, and centromeres are structures found in eukaryotic cells that help to separate chromosomes during cell division.
