Which of These Statements Best Describes Pseudogenes

Question

Which of these statements best describes pseudogenes?
A) Most pseudogenes derived from protein-coding genes but are not recognized by their sequence similarities to functional genes.
B) Pseudogenes are short repetitive sequences.
C) Pseudogenes are not similar to functional genes at DNA sequence level.
D) Most pseudogenes are derived from protein-coding genes and are recognized by their sequence similarities to functional genes.

Accepted Answer

Pseudogenes are indeed derived from protein-coding genes and are recognized by their sequence similarities to those functional genes. However, they are typically non-functional due to mutations that prevent them from being properly expressed.
