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).
Translation is where the mRNA is being translated into a protein. You need mRNA for sure which is the message that needs to be translated. tRNA is the transfer protein. Ribosomes attach the mRNA and tRNA to make the protein. DNA is needed for all this to happen. However it is not part of translation process itself. Guanisine Triphospate is version of ATP. GTP and DNA are not directly involved in the translation process.
