Cytoplasm consists of the complete contents of a biological cell, excluding the nucleus, whichcontains the organism’s DNA. In plants and animals, the cytoplasm includes the fluid known as cytosol, the supportive structure known as the cytoskeleton.

Extrachromosomal DNA is any DNA that is found outside the nucleus of a cell. It is also referred to as extranuclearDNA or cytoplasmic DNA.

Recombinant DNA molecules are sometimes called chimeric DNA, because they can be made of material from two different species, like the mythical chimera. R-DNA technology uses palindromic sequences and leads to the production of sticky and blunt ends.
