Verified step by step guidance
1
Understand the concept of genome structure: In biology, a genome is the complete set of DNA, including all of its genes. Organisms can have different types of genome structures, such as linear or circular chromosomes.
Identify the typical genome structure for different organisms: Humans, plants, and fungi typically have linear chromosomes, whereas bacteria often have a singular circular chromosome.
Recognize the characteristics of bacterial genomes: Bacteria are prokaryotic organisms, and their genomes are usually composed of a single circular chromosome, which is different from the linear chromosomes found in eukaryotic organisms like humans, plants, and fungi.
Consider the evolutionary and functional reasons: The circular chromosome in bacteria is advantageous for their replication and survival, allowing for efficient replication and repair processes.
Conclude with the correct identification: Based on the understanding of genome structures, bacteria are the organisms that typically have genomes composed of a singular circular chromosome.
