You have isolated a fragment of DNA that totally encodes at least two proteins, 120
and 80 amino acids long. The DNA fragment is 400 base pairs long. (A) Why might
you consider this unusual? (B) You sequence th two proteins and find no homology.
Propose a model to account for these findings

The two proteins of 120 and 80 amino acids long, need at least 600 base pairs in order to encode the proteins, therefore encoding on a 400 base pair strand is unusual.

Explanation:

It is possible that there has been a frameshift, therefore the interpretation of two separate reading frames has resulted in two different proteins.
