Using a pre-drawn template can be helpful during a consultation to explain single gene inheritance. Our template shows one pair of chromosomes for each parent. Each chromosome has a single gene highlighted that can be coloured in to illustrate a gene alteration. You can then show which sperm and/or eggs contain the chromosome with the gene alteration and the different genetic combinations that could be present at conception.

LDC lesson on CER with examples and templates

The structure of DNA, discovered by James Watson and Francis Crick, suggests a mechanism of replication. The double helix unwinds, and each strand acts as a template for the construction of the new DNA molecule.

The possibilities of pseudo-peptide-DNA mimics like PNA (peptide nucleic acid) having a role for the prebiotic origin of life prior to an RNA world is discussed on the basis of literature data showing that this type of molecules might have formed on the primitive earth (or other places in the universe), as well as data indicating the possibilities of template-directed PNA chemical replication and ligation. In particular, the merits of an achiral prebiotic genetic material is discussed.

But this tiny sample turned out to hold tremendous scientific value. It was from a person fortunate to survive the deadly Ebola virus outbreak of 2014. Walker and her colleagues wanted to know if they could identify some special antibodies in that person's blood. If this person had special Ebola-neutralizing antibodies, that might help explain why that person lived. The antibodies might also help provide a template for future development of a vaccine. Or, they could be the basis for genetically engineered copies that could be manufactured at large scale, stockpiled and used to rescue people newly infected in an outbreak.
