You seem confused. RNA polymerase is the enzyme that transcribes DNA into pre mRNA. So, the enzyme would transcribe the messenger RNA for its own protein construction.
Enzymes are biological catalysts so Amylase, Maltase, Protease, Lipase. Yeast is also a biological catalyst.
chromosomes contain there own RNA(ribo nucleic acid).therefore they are able to make there own proteins.
Yes, chloroplasts (plastid) in plants, algae and some protists and mitochondria of all Eukaryotes containing their own DNA that produce RNA and make proteins. They thought to be originated as a result of endosymbiosis!
RNA is not considered as genetic material except a group of viruses. RNA can not make DNA in human or microbes (except virus). RNA is not a molecule responsible to function as biocatalysts that are responsible to drive cellular processes.
Thomas R. Cech showed that RNA could act as its own catalyst. His work changed scientific opinion that all enzymes were proteins.

This compound is an active homogeneous epoxidation catalyst in its own right.
Mitochondria and chloroplasts have their own DNA and RNA.Genes along the DNA are transcribed, so messenger RNA (mRNA) is formed, and there is (ribosomal RNA) rRNA in ribosomes. These organelles have their own transfer RNA (tRNA) molecules, too.
The prevailing idea among molecular biologists is that RNA came first, in an "RNA world".There are several arguments used to support this idea. One is that DNA needs RNA in order to replicate, but RNA can replicate itself. Also RNA has catalytic properties; DNA does not. The first nucleic acid must have been able to replicate itself and to catalyze the process.Another line of evidence involves the way that most cells synthesize the components of the two nucleic acids. The nucleotides of RNA (ribonucleotides) are assembled from simpler molecules, but those of DNA are produced by modification of ribonucleotides (the sugar of the ribonucleotide, ribose, is reduced to form deoxyribose, and if the base in the nucleotide is uracil it is methylated to form thymine).

Romeo goes to him for advice about his love life, both concerning Juliet and, as is apparent from their conversation, about Rosaline. It is the friar that Romeo flees to after killing Tybalt, not his own family. In fact, we never see him interacting with his parents during the entire play. Nevertheless his mother dies of grief about not being able to see this son who she never sees anyway.
The DNA molecule in the nucleus makes a copy of itself using RNA, this is Messenger RNA. The Messenger RNA travel to a Ribosome. There is Transfer RNA floating about the cytoplasm. This is short (only three base pairs long) pieces of RNA that have their own unique amino acid attached to them. The Transfer RNA links up with the Messenger RNA according to their mutually compatible base pairs. The amino acids that the Transfer RNA is carrying link up with each other and detach from the Transfer RNA this is the beginning of a protein chain.

The genetic material that viruses have is RNA. Viruses are unable to truly carry out the processes associated with holding their own DNA.
