Describe 2 homologies (structures that were shared from a common ancestor) between the Zeuglodon and the Orca.

Homologous structures can be described structures which originate in different organisms from a common ancestor and may or may not have the same functions.

Zeuglodons can be described as ancient whales and Orca is a common whale today known as the killer whale.

Scientific studies show that Zeuglodans and Orca have many structures in common such as:

The sequence of DNA may be associated with the sequence of amino acids, and the sequence of amino acids to the three-dimensional shape of the protein. It is the sequence of DNA, which provides the code for the amino acid sequence, and the sequence of amino acids further determines the protein structure that further influences the function of the protein.

When the sequence of DNA changes it causes a change in the sequence of mRNA, further resulting in the change in the sequence of DNA's nucleic acid and the sequence of amino acid. The sequence of amino acids of a protein is accountable for the composition of the protein. The composition of a protein is accountable for its function. The function and composition of a protein are primarily accountable for the organism's trait.
