Answer Wiki. 1 Answer. It's a term of endearment, a nickname you might call your husband/girlfriend/boyfriend/wife. I haven't heard it used for real in several decades; it might be kind of archaic.

DNA is mainly only found in the nucleus (if we disregard mitochondrial DNA). RNA is found in both nucleus and cytoplasm, as it is synthesized from the DNA template in the nucleus but is addressed to the cytoplasm, like a letter, a message (hence mRNA m for messenger) where it is translated into a protein by the ribosome.
nuclear DNA (nDNA) the DNA of the chromosomes found in the nucleus of a eukaryotic cell. recombinant DNA DNA artificially constructed by insertion of foreign DNA into the DNA of an appropriate organism so that the foreign DNA is replicated along with the host DNA.
