According to Orgel's error theory, an error in what is suggested to be the first step in aging?

Orgel's error theory posits that aging is fundamentally linked to errors that occur during the process of protein synthesis. According to this theory, the accumulation of these errors over time leads to the production of malfunctioning proteins, which can disrupt cellular function and contribute to the aging process. As proteins play crucial roles in virtually every cellular process, any mistakes in their synthesis can have widespread impacts on the organism's health and aging.

The other choices do not directly relate to the central premise of Orgel's error theory. Environmental pollutants may influence health and aging but are not the focus of this specific theory. Iron synthesis, while important for overall health, is not directly tied to the mechanisms of aging that Orgel proposed. Similarly, global warming is a significant environmental issue but does not pertain to the biological processes of aging as described in Orgel's work. The emphasis on errors in protein synthesis is what sets this theory apart in explaining the initial steps of the aging process.
