Biosynthesis of proteins occurs in the cytoplasm of eukaryotic cells by taking information of the original DNA or the DNA gene that stays in the nucleus of the cell.
The DNA, or gene, present in the cell nucleus, dictates the sequence of the protein to be synthesized.
The process protein biosynthesis occurs in two steps: transcription and translation.
Transcription is the synthesis of mRNA having the same sequence as the DNA strand it is made from.
The matured mRNA comes out of the nucleus into the cytoplasm through a process called splicing.
Translation is the conversion of mRNA to protein with the help of tRNA and ribosomes.
The Ribosome provides a platform on which the peptide synthesis can take place.
Ribosomes are an assembly of proteins, plus the ribosomal RNA.
