Question

question 6 of 10
which of the following correctly describes a plasmid?
a. a small, circular rna molecule that inserts itself into a
chromosome
b. a small, circular rna molecule that replicates independently of
the chromosomes
c. a small, circular dna molecule that replicates independently of
the chromosomes
d. a small, circular dna molecule that inserts itself into a
chromosome

Explanation:

Plasmids are small, circular DNA molecules. They are not RNA (so A and B are wrong). They replicate independently (not by inserting into chromosomes, so D is wrong). This matches option C.

Answer:

C. A small, circular DNA molecule that replicates independently of the chromosomes
