The genome of an organism does not contain which of the following elements?

A) proteins
B) pseudogenes
C) protein-coding genes
D) mobile genetic elements

Pseudogenes

Segments of DNA that are similar to active genes but have lost their ability to code for proteins, often due to mutations.

Protein-Coding Genes

Genes that contain the instructions within their DNA sequence to build proteins, which perform most life functions and make up the majority of cellular structures.

Mobile Genetic Elements

Segments of DNA that can move or copy themselves to new positions within the same or a different genome, playing a crucial role in evolution and genetic diversity.
