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).
1 Transcription-specialized proteins attach to the DNA strand and make a copy of the DNA sequence in the form of a molecule called messenger RNA (mRNA). 2  The genetic message is transferred outside the nucleus via mRNA. 3  Translation-Cellular machinery reads the genetic instructions in the mRNA and synthesizes proteins.hese steps are: 1  Transcription-specialized proteins attach to the DNA strand and make a copy of the DNA sequence in the form of a molecule called messenger RNA (mRNA).
