Outline the series of steps that transfers genetic information from the linear sequence of nucleotides in a DNA molecule into the linear sequence of amino acids in a protein
What will be an ideal response?
During the first step the information encoded in a gene is copied into an RNA molecule known as pre-messenger RNA (pre-mRNA). This step is called transcription and takes place in the nucleus. Next, the pre-mRNA is then processed into a finished messenger RNA (mRNA) that moves through a nuclear pore into the cytoplasm. Here, during the third step called translation, the information encoded in the mRNA is converted into the sequence of amino acids in a polypeptide chain, which is processed and folded to form a protein.
