0845 numbers, for example, are free to call for up to an hour, during the inclusive minutes of your call package if you're a BT customer. Yet call an 0844 number and you'll be charged up to 5.1p/minute, plus a connection fee of up to 15p.
The resulting mRNA is a single-stranded copy of the gene, which next must be translated into a protein molecule. During translation, which is the second major step in gene expression, the mRNA is read according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins (Figure 2).
DNA is made up of nucleotides, and proteins are made up of amino acids. The information in DNA is first transcribed into messenger RNA (mRNA) , which is also made up of nucleotides. The process of converting the genetic message found in mRNA to an amino acid sequence (protein synthesis) is called translation.longation continues in this fashion until the stop codon is reached and the peptide chain is released from the ribosome. Translation of proteins involves a mRNA, tRNA, ribosome, and energy. Click on the graphic to learn about translation with the Protein Synthesis animation.
