Which is the term for replicating circular pieces of dna that often carry antibiotic-resistant genes

The answer is Plasmid, these are circular pieces of DNA that can carry genes beneficial to the organism such as antibiotic-resistant genes and can self-replicate. Unlike Viruses that are covered with capsid, Plasmids don’t need close or envelope their general material.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
