How is genetic information organized in eukaryotic chromosomes?
Understand the Problem
The question is asking about the organization of genetic information in eukaryotic chromosomes, specifically how genes are arranged within these chromosomes. The options provided suggest different possible arrangements.
Answer
In eukaryotes, genetic information is organized into linear chromosomes made of chromatin, containing nucleosomes.
In eukaryotes, genetic information is organized as linear chromosomes within the nucleus. These chromosomes consist of a DNA-protein complex called chromatin, which is organized into subunits known as nucleosomes.
Answer for screen readers
In eukaryotes, genetic information is organized as linear chromosomes within the nucleus. These chromosomes consist of a DNA-protein complex called chromatin, which is organized into subunits known as nucleosomes.
More Information
Eukaryotic cells differ from prokaryotic cells in that their chromosomes are housed within a nucleus. The organization into nucleosomes helps efficiently package the DNA, allowing it to fit within the cell's nucleus.
Tips
A common mistake is confusing prokaryotic and eukaryotic chromosome organization. Remember that eukaryotes have linear chromosomes in a nucleus, while prokaryotes have circular chromosomes in the cytoplasm.
