What is the definition of a “genome”?

Question

BlackTom AI · Accepted Answer

To understand the concept, let's break down what a genome encompasses. The genome refers to the complete set of genetic material present in an organism or cell.
Option 1 posits that a genome is merely the specific location of a gene on a chromosome. This describes a gene’s locus, not the entire genome, so it omits all other genetic material and regulatory regions.
Option 2 states: 'The entire genetic information of an organism including coding and non-coding DNA sequences.' This aligns with the standard definition, capturing both the protein-coding regions and the many non-coding regions that regulate expression and other functions.
Option 3 says: 'All the DNA sequences that encode for proteins or RNA sequences in an organism.' While this covers coding sequences and some functional elements, it excludes non-coding DNA that has regulatory or structural roles, which are still part of the genome.
Option 4 describes 'the set of observable characteristics of an organism,' which defines the phenotype, not the genome itself; genetics explains how those traits arise, but the genome is distinct from the phenotype.
Thus, option 2 best captures the comprehensive concept of a genome, including both coding and non-coding DNA, while the other choices describe related but narrower ideas or incorrect facets.
