Rate variation during molecular evolution: creationism and the cytochrome c molecular clock [PDF]

, 2017
Molecular clocks based upon amino acid sequences in proteins have played a major role in the clarification of evolutionary phylogenies. Creationist criticisms of these methods sometimes rely upon data that might initially seem to be paradoxical.

Radiothermometric Study of the Effect of Amino Acid Mutation on the Characteristics of the Enzymatic System

Diagnostics, 2022
The radiothermometry (RTM) study of a cytochrome-containing system (CYP102 A1) has been conducted in order to demonstrate the applicability of RTM for monitoring changes in the functional activity of an enzyme in case of its point mutation. The study has
