Describing things that have a similar position or structure because they are from the same ancestor.
The flippers of dolphins and the arms of humans are homologous - they have the same basic structure because they were inherited from a common ancestor.

Biology Focus
Used to describe similarities in living beings due to shared ancestry.

In biology class, we learned that homologous limbs indicate common evolution.
Structure Over Function
Emphasizes structure similarity, even if functions differ.

Although used for flying, the homologous structures of bird wings and human hands are evident.
Evolutionary Evidence
Suggests evidence of evolution in comparative anatomy.

Scientists use homologous bones to trace the evolution of vertebrates.

but it's not the way that we really want to do genome editing. The second repair pathway is a lot more interesting. In this repair pathway, it takes a homologous piece of DNA. And now mind you, in a diploid organism like people, we've got one copy of our genome from our mom and one from our dad,

Double strand breaks are the most dangerous. Even one can cause cell death. The two most common pathways for repairing double strand breaks are called homologous recombination and non-homologous end joining.
