Is DNA transcribed only to mRNA or also to tRNA and rRNA?

Answer 1

To clarify all these confusing answers here.
DNA encodes genes. These genes are transcribed into hnRNA, not, and this is important, not mRNA. It only becomes mRNA when it is modified leaving the nucleus, and so mRNA is NOT transcribed from DNA.

DNA also encodes functional RNA's. These are:
tRNA's - transfer RNA that carry amino acids used to make proteins

rRNA - ribosomal RNA's, the functional part of a ribosome

sRNA - small sequences of RNA's that have varoius functions.

Answer 2

Hi:

DNA is transcribed from the Sense strand into messenger RNA, and as the name indicates, this RNA carries the genetic info from the DNA to proteins, you know, the Central Dogma of Molecular Biology.

Contrary to the other answers here, well as of now anyways, DNA is ALSO read into tRNA and rRNA. A gene is defined as a specific stretch of DNA that codes for proteins (like in the conventional definition), tRNA and rRNA. Where else would these come from.... mRNA?

So the answer to your question is an emphatic YES!

Answer 3

DNA is transcribed to tRNA and rRNA also, but these RNAs are not translated into proteins.

(tRNA shuttles amino acids to the ribosome, rRNA forms active parts of the ribosome itself).

They are indeed transcribed (by RNA polymerase III for rRNA) and not by "other processes".

Large transcripts are produced and then trimmed to form the smaller, final structural RNA components.

Answer 4

The first step is to produce a linear copy of DNA called PRIMARY TRANSCRIPT. The primary transcript already contains small RNAs. In eukaryotic genes, this primary transcript then undergoes extensive POST-TRANCRIPTIONAL MODIFICATION to form the final mRNAs, tRNAs, or rRNAs.

Answer 5

DNA is genetic information, therefore only transcribed to mRNA. there are other processes to produce tRNA and rRNA.

Answer 6

DNA transcribe all forms of RNA: tRNA, mRNA, rRNA, snRNA, hnRNA, mi or siRNA. It all comes from DNA.
