Verified step by step guidance

Understand the structure of the human genome: The human genome consists of approximately 3 billion base pairs of DNA.

Recognize the role of protein-coding genes: Only a small portion of the genome is made up of protein-coding genes, which are sequences that are transcribed into mRNA and then translated into proteins.

Identify non-coding regions: The majority of the genome consists of non-coding regions, including introns, regulatory sequences, and non-coding RNAs, which do not directly code for proteins.

Consider the percentage of the genome that is protein-coding: It is estimated that only about 1-2% of the human genome actually encodes for proteins.

Conclude based on the evidence: Given that the majority of the genome is non-coding, the statement that the majority of the human genome encodes for proteins is false.
