"False.
(I found the answer in my Biology textbook)"
Not true. An operon is technically more than one gene sequence that is controlled by a repressor or signal. Recent research into eukaryotic genes, especially those in protists and chordates, have revealed that eukaryotes also have operons, though they are slightly different in complexity to the ones found in prokaryotes, giving rise to the conclusion that operons are more common than expected.
What else can I help you with?
What organisms have operons?
Operons appear most in prokaryotes, however can also be found in some eukaryotic organisms such as the nematode. The nature of this is because operons produce polycistronic mRNA, which is used mostly by bacteria, whereas eukaryotes use monocistronic mRNA.
What are the differences in gene expression regulation between eukaryotes and prokaryotes?
In eukaryotes, gene expression regulation is more complex and involves multiple levels of control, such as chromatin remodeling, transcription factors, and post-transcriptional modifications. Prokaryotes, on the other hand, have simpler regulation mechanisms, mainly involving operons and transcription factors.
Are hox genes regulated by operons?
No, hox genes are not regulated by operons. Operons are found in prokaryotes and involve a group of genes that are transcribed together under the control of a single promoter. Hox genes are a group of eukaryotic genes that play a key role in embryonic development and are regulated by complex mechanisms involving enhancers and other regulatory elements.
What are the key characteristics of haploid eukaryotes and how do they differ from diploid eukaryotes?
Haploid eukaryotes have one set of chromosomes, while diploid eukaryotes have two sets. This means haploid cells have half the genetic material of diploid cells. Haploid eukaryotes are typically found in reproductive cells, like sperm and eggs, while diploid eukaryotes are found in most other cells of the body.
What structure is present in eukaryotes but not in prokaryotes?
dna
What organisms have operons?

How is protein synthesis different in prokaryotes and eurkaryotes?
One way that protein synthesis differs between prokaryotes and eukaryotes is that gene groups that produce proteins are organized into operons in prokaryotes, but they are not organized into operons in eukaryotes. Also, protein synthesis in eukaryotes involves more protein and is a more intricate process than in prokaryotes.
Is the lac operon found in prokaryotes or eukaryotes?
The lac operon is found in prokaryotes, specifically in bacteria such as Escherichia coli. It is a regulatory system that controls the expression of genes involved in lactose metabolism. Eukaryotic cells do not typically have operons like the lac operon.
Eukaryotic DNA sequences called enhancers have a function similar to the of prokaryotic operons?
Eukaryotic DNA sequences called enhancers have a function similar to the operators of prokaryotic operons. In eukaryotic cells, repressor proteins inhibit transcription by binding to silencers.
2 types of operons?
The two types of operons are Inducible and Repressible Operons.
Is cytoplasm in eukaryotes or prokaryotes?
cytoplasm is found in both eukaryotes and prokaryotes.
Do mitochondria have introns?
Yes, mitochondria have introns. These introns are non-coding sequences found within the DNA of the mitochondria. They are typically removed during the process of RNA splicing to produce functional mitochondrial mRNA.
Where are choloroplasts found?
They are found in eukaryotes only. They are in cytoplasm.
What are the differences in gene expression regulation between eukaryotes and prokaryotes?

What cell type is smooth endoplasmic reticulum found?
they are found in Eukaryotes
Is eukaryote found in goldfish cells?
Yes. Eukaryotes are found in animals
