Molecular evolution investigates the processes that drive changes in genetic material over time. It encompasses the generation of mutations—whether through DNA replication errors, damage or other ...

The molecular clock theory posits that genetic changes happen steadily and gradually, offering a reliable means for peering into the past and theorizing when complex life first emerged. However, there ...

Introduction -- A pattern emerges: early comparison of amino acid sequences -- A theory to match: the neutral theory of molecular evolution predicts a molecular clock -- Generation gap: the theory is ...

Circadian pacemaker neurons in the Drosophila brain display daily rhythms in the levels of intracellular calcium. These calcium rhythms are driven by molecular clocks and are required for normal ...

A new study led by UC Santa Cruz researchers has found that a protein associated with cancer cells is a powerful suppressor of the biological clock that drives the daily (“circadian”) rhythms of cells ...

Here’s what you’ll learn when you read this story: The molecular clock theory posits that genetic changes happen steadily and gradually, offering a reliable means for peering into the past and ...
