Answer:

C. A small, circular piece of DNA

Explanation:

A plasmid, usually circular but sometimes linear, is a small double-stranded DNA unit, which is chromosome independent and is capable of self-replication. Each plasmid carries only a few genes. Carrying only a few genes, the plasmid’s size ranges from 1 to more than 1000 kbp. Genes required for organism survival and those that are generally beneficial to the host organism, such as antibiotic resistance, are often found in plasmids [1].

Mostly plasmids can be found in bacteria, but they are also present in multicellular organisms and archaea. Plasmids usually contain at least one gene and are not considered independent life forms even though they possess separate genes from their hosts

The answer is C.
A plasmid is a small, often circular DNA molecule found in bacteria and other cells. Plasmids are separate from the bacterial chromosome and replicate independently of it. They generally carry only a small number of genes, notably some associated with antibiotic resistance.

What would need to happen for copper not to not exsist anymore.
san4es73 [151]

Electricity could be discovered using batteries based on zinc or lead, but without copper wiring it would remain little more than a scientific curiosity. Electric motors and generators require large amount of wiring, so they are impossible to build on large scale in this world
