Messenger RNA (mRNA) is synthesized during transcription in the nucleus before transfer RNA (tRNA) comes into play during translation in the cytoplasm. So, mRNA is produced first in the sequence of events.
RNA
most likely RNA
RNA likely came first in the evolution of life before DNA. RNA is thought to have been an early molecule that played a crucial role in the development of life on Earth.
RNA is thought to have emerged first as the molecule capable of both storing genetic information and catalyzing chemical reactions. This hypothesis is known as the "RNA world" theory, which suggests that RNA was the precursor to both DNA and proteins in early life forms.
it goes to the nucleus
First off you should get a pre med or go to nursing school. After nursing school you will be able to do RNA training to become a CRNA. IMPORTANT that you have at least a 3.0 before you apply to an RNA training program.
RNA polymerase is the enzyme responsible for linking RNA nucleotides together during transcription. It catalyzes the formation of phosphodiester bonds between nucleotides to create a single-stranded RNA molecule.
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).
After transcription is completed, RNA goes through a process called RNA processing, where it is modified and prepared for translation. The processed RNA then leaves the nucleus and enters the cytoplasm, where it can be used to make proteins during translation.
No, that's the job of the RNA.
The first step in decoding genetic messages is transcription, where the DNA sequence is copied into a messenger RNA (mRNA) molecule by RNA polymerase.
