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).
Review of Codon Recognition. Translation is the process of converting the genetic information in the mRNA strand to the form of a protein. The basic unit of this genetic information is a codon. Earlier, we described a codon as a sequence of three nucleotide bases that specifies a particular amino acid.ince both the amino acid and the mRNA codon bind to the tRNA, then they can be brought together as an appropriate match. Just to be sure we've got everything clear, let's try an example of genetic translation. We've done it before, but this time we'll bring tRNA and the anticodons into the picture.
