Question

List two types of molecules that can be used to show an evolutionary relationship. What is their function?

Answer 1

:)

Step-by-step explanation:

Evolutionary Relationships

Regulatory genes (e.g. coding for protein-based hormones)

Genes encoding for tRNA (needed for translation to occur)

Genes involved in ATP production (e.g. coding for the cytochrome proteins in the electron transport chain)

Answer 2

Mitochondrial DNA

Scientists can use the DNA from mitochondria, our cell's energy powerhouses, to construct evolutionary relationships among humans. Mitochondria have their own DNA rather than taking their form from human genetic information

Homologous structures. Structures that have different mature forms, develop from the same tissue.

Analogous structures. Similar mature form but do not have similar body structures.
