introns and exons
Genes are sections of DNA that control different traits. When the DNA is transcribed to mRNA, then translated by a ribosome, the ribosome is DIRECTLY synthesizing the protein from the mRNA. This means that the genetic code on the DNA directly corresponds to the type of protein that is being made!
if i understand your question right, polymerase is my guess
RNA molecules
There are different types of genes for encoding three types of RNA. Protein coding genes are transcribed by RNA polymerase II to yield mRNA. Ribosomal RNA (rRNA) are transcribed by RNA polymerase I. Likewise, transfer RNA (tRNA) are transcribed by polymerase III.
I belive is DNa.
CISTRON
No. This is why you have different types of cells.

DNA...which comprises genetic information. When transcribed and translated, it forms many different genes. One or more genes code for a given trait.
Genes are transcribed to make Proteins

All cells have genes
initially its hrRNA or pre-mRNA. (same thing different name). this then undergoes some modification like splicing, capping and polyadenalation to make mRNA which is then translated into protein.
RNA molecules
They are operons. The genes contained in an operon are expressed together or not at all.

Yes. A protein produced by multiple genes are cased by fusion genes. Usually a protein is translated from a mRNA which is transcribed from a DNA. After transcription, RNA is rearranged by so-called RNA splicing in which some of short sequences are selected(Exon) or deleted(Intron). During the splicing two different genes can join together and it is called trans-splicing. After trans-splicing, mRNA is translated into a protein, so the protein has two genes. Most cases these fusion genes are oncogenes which cause Cancerous diseases.
