Some of the most interesting papers I’ve found so far in my cataloguing of the Institute of Animal Physiology and Genetics Research (IAPGR) have been the ones on gene sequencing, molecular cloning and analysis. This is the first paper I’ve come across so far that shows an animal gene sequence next to a human one.

This image of a genomic sequence (Figure 3) in D. H. Fawcett and G. Bulfield’s article, ‘Molecular cloning, sequence analysis and expression of putative chicken insulin-like growth factor-I cDNAs’ in the Journal of Endocrinology (1990), 4, 201-211 shows the ‘potential splice donor sites at the excon 2 (5’) intron boundary in the chicken compared with the corresponding human sequence and the chicken and human cDNAs.’
