What is the major difference between bacterial chromosomes and eukaryotic chromosomes?
A
The DNA molecules of bacterial chromosomes have a slightly different structure than those of eukaryotic chromosomes.
B
Eukaryotes have a single circular chromosome, whereas bacteria have several linear chromosomes.
C
Bacterial chromosomes have much more protein associated with the DNA than eukaryotes.
D
There is no difference between bacterial and eukaryotic chromosomes.
E
Bacteria usually have a single circular chromosome whereas eukaryotes have several linear chromosomes.
Verified step by step guidance1
Understand the basic structure of chromosomes in both bacteria and eukaryotes. Bacterial chromosomes are typically circular, whereas eukaryotic chromosomes are linear.
Recognize that bacteria usually have a single circular chromosome. This is a key feature that distinguishes them from eukaryotes.
Identify that eukaryotic cells generally contain multiple linear chromosomes. This allows for more complex organization and regulation of genetic material.
Consider the role of proteins associated with DNA. Eukaryotic chromosomes have histone proteins that help in packaging the DNA into chromatin, whereas bacterial chromosomes have fewer associated proteins.
Conclude that the major difference between bacterial and eukaryotic chromosomes is their shape and number: bacteria have a single circular chromosome, while eukaryotes have multiple linear chromosomes.
