In Translation, rRNA, tRNA, and mRNA are used. The mRNA strand of codons (3 nucleotide bases) enters the ribosome where the rRNA will "read it" (it is made up of rRNA). tRNAs are floating in the cell carrying the anticodon's specified amino acid. When the rRNA "sees" which codon is on the mRNA strand, the tRNA's anticodon (complementary nucleotide bases) binds to the A site in the ribosome to start creating the polypeptide chain.
mRNA which stands for messenger RNA with introns. mRNA's are the blueprints for proteins but after transcription some stepps have to be taken for the mRNA to be used in eukaryotes.
First a 5' cap is added. This is recognition sequence that is added in front of the molecule so it can be recognized later as mRNA by ribosomes
Then splicing occurs not all nucleotides encode for a protein but only and these are cut away.
Polyadenylation at 3' end many A's are added to mark end of transcription and is important for transport of the moleculeTranscriptions occurs in the nucleus of a eukaryotic cell; in the cytoplasm of a prokaryotic cell.
mRNA. Called messenger RNA.

During the process of transcription messenger RNA represents a polypeptide. This comes encoded and in a wide array of sizes.
Transcription

transcription
During transcription an RNA Molecule is formed inside the nucleus. The DNA is too large to leave the nucleus and participates directly in the cytoplasmic protein synthesis. It is necessary to make a small copy of Messenger RNA that will migrate out of the nuclear pore in to the cytoplasm.
During transcription a protein molecule called a messenger RNA, or mRNA, is produced. This protein becomes important later during translation.
A persistent RNA-DNA hybrid is formed during transcription at a phylogenetically conserved mitochondrial DNA sequence.
RNA polymerase is the enzyme that adds and links complementary RNA nucleotides during transcription
