Genetics and biotechnology

A collection of post 16 resources which cover biotechnology, DNA sequencing and  gene therapy.  These resources are part of the post 16 genetics and genomics collection.


Di-deoxy sequencing gel with annotation

Di-deoxy sequencing is a way to determine the order of bases (A,C,G and T) in a piece of DNA.  A set of 4 lanes (one for each base) is needed to sequence any given piece of DNA. Wherever a black band appears in a particular lane...

Human genome sequencing

The public Human Genome Project started by identifying unique marker sequences distributed throughout the genome. Then, many copies of a small section of DNA were randomly cleaved into smaller fragments, and each small fragment was sequenced. Because there were originally many copies of the DNA in question, many...

Polymerase chain reaction (PCR)

Polymerase chain reaction (PCR) enables researchers to produce millions of copies of a specific DNA sequence in approximately two...

Sanger method of DNA sequencing

Fred Sanger developed the first technique for sequencing DNA. DNA is replicated in the presence of chemically altered versions of the A, C, G, and T bases. These bases stop the replication process when they are incorporated into the growing strand of DNA, resulting in varying lengths of short DNA. These short DNA...
