Chapter 3: Problem 16

Cite two pieces of evidence that genes control aging.

Short Answer

Expert verified
Two pieces of evidence that genes control aging include genetic studies on Caenorhabditis elegans showing that mutations in certain genes (e.g., daf-2) can extend the organism's lifespan and human genomic studies indicating a link between certain gene variants (e.g., APOE and FOXO3) and exceptional longevity.

Step by step solution

01

Identify Genetic Evidence 1

The first piece of evidence can be genetic studies on Caenorhabditis elegans. In these studies, mutations in the daf-2 gene, which encodes for the insulin-like growth factor 1 (IGF-1) receptor, can actually double this organism's lifespan. Beginning with this evidence highlight that genetic factors play a significant role in aging.
02

Identify Genetic Evidence 2

The second piece of evidence comes from studies on human genomes. The study of centenarians has shown certain genes or gene variants are associated with exceptional longevity - such as APOE and FOXO3. This suggests that our genes can directly affect our lifespan and influence aging.
