The exome is the part of the genome composed of exons. In RNA, introns are removed by RNA splicing. That leaves the sections of the RNA which actually code for the final protein. Exome sequencing is the way researchers find the causes of many inherited diseases.
Exome
Questions and Answers
Q: What is the exome?
A: The exome is the portion of the genome that consists of exons.
Q: What are exons?
A: Exons are the sections of DNA or RNA that code for proteins.
Q: What happens to introns during RNA splicing?
A: Introns are removed by RNA splicing.
Q: What is RNA splicing?
A: RNA splicing is a process by which the non-coding regions, or introns, are removed from RNA strands.
Q: What is the purpose of exome sequencing?
A: Exome sequencing is a method used by researchers to identify the causes of inherited diseases.
Q: How does exome sequencing work?
A: Exome sequencing involves sequencing only the exons of genes in a genome, rather than the entire genome.
Q: Why is exome sequencing more efficient than whole genome sequencing?
A: Exome sequencing is more efficient than whole genome sequencing because it only sequences the exonic regions of genes, which make up only about 1-2% of the genome.
