Function of mRNA The mRNA is formed inside the nucleus in a process called transcription. This mRNA contain codon responsible for the formation of specific type of protein. In translation this mRNA is converted into protein. Function of tRNA tRNA is found in cytoplasm and possess amino acids. During translation they attach to the base pair of mRNA with the help of anti-codons.
Formation rRNA: rRNA is the principle component of ribosome. Ribosome is that organelle which help in attachment of mRNA and contribute in translation.
