Course Description

This unit explores how information contained in DNA is used, explaining the flow of information from DNA to RNA to protein. Also introduced are the concepts of transcription (as occurs between DNA and RNA) and translation.

Learning Outcomes

After studying this unit you should understand:

how the linear sequence of DNA within a gene is related to the linear sequence of amino acids of a protein
how the information in DNA is carried via RNA to make a protein
how RNA is synthesised from DNA by the process of transcription
where the processes of transcription and translation occur within the cell

	Introduction Introduction Resource This unit explores how information contained in DNA is used, explaining the flow of information from DNA to RNA to protein. Also introduced are the concepts of transcription (as occurs between DNA and...

	Using information stored in DNA One gene–one protein Resource A gene is a short section of a long DNA double helix molecule, which comprises a linear sequence of base pairs. The flow of information from DNA to RNA to protein Resource The information flow from DNA to protein is more complex than shown in Figure 1. The genetic information encoded within the DNA of a gene is carried via an intermediary molecule, RNA (ribonucleic acid).... From DNA to RNA: transcription Resource In the process of transcription, the information in a gene, i.e. the DNA base sequence, is copied, or transcribed, to form an RNA molecule. RNA is therefore an intermediary in the flow of information from... Where does transcription occur in the cell? Resource Up to now we have described the processes of transcription without considering where each occurs within the cell.
