Description

Telomeres isolated from chicken erythrocyte nuclei following restriction endonuclease treatment, and imaged by transmission EM after uranyl acetate negative staining. Sample was also labeled for the telomere protein TRF1 using immunogold. Image recorded with FEI Tecnai 12 TEM at 100KV and recorded on 2048x2048 CCD with 2x binning. Telomeres have a looped conformation, which likely aids in their protection from the rapid degradation that occurs with free DNA ends.
