The macromolecular complex that facilitates RNA splicing in eukaryotes is the spliceosome. This dynamic assembly is composed of small nuclear ribonucleoproteins (snRNPs) and numerous associated proteins. The spliceosome catalyzes the removal of introns from pre-mRNA and the joining of exons, allowing for the production of mature mRNA transcripts. This process is essential for proper gene expression and the generation of functional proteins.
What else can I help you with?
Which method is utilized by eukaryotes to control their gene expression that is not used in bacteria?
Eukaryotes utilize mechanisms such as chromatin remodeling, alternative splicing, and RNA interference to regulate gene expression, which are not commonly used in bacteria. These mechanisms allow for more complex and nuanced control of gene expression in eukaryotic cells.
Do eukaryotes have Golgi apparatus?
They are the more complex cells.
What is the kingdom of the Eukaryotes?
Kingdom Protista contains complex single-celled organisms.
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.
What is unique about thr DNA of eukaryotes?
Eukaryotic DNA is unique due to its structure and organization; it is linear and organized into multiple chromosomes housed within a membrane-bound nucleus. Additionally, eukaryotic DNA contains introns and exons, allowing for more complex gene regulation and splicing. Eukaryotes also have mitochondrial DNA, which is circular and inherited maternally, contrasting with the nuclear DNA. This complexity contributes to the greater diversity and functionality of eukaryotic organisms compared to prokaryotes.

What types of molecules catalyze RNA splicing?
Small nuclear ribonucleoproteins (snRNPs) are the main group of molecules that catalyze RNA splicing. These snRNPs consist of both RNA and protein components, and they play a crucial role in the spliceosome complex, which is responsible for catalyzing the removal of introns and joining of exons during pre-mRNA processing.
Do eukaryotes have Golgi apparatus?
They are the more complex cells.
What are more complex cells called other then prokaryote?
eukaryotes
In what ways do eukaryotes and prokaryotes differ from each other?
Eukaryotes have a nucleus and other membrane-bound organelles, while prokaryotes do not. Eukaryotes are typically larger and more complex than prokaryotes.
What cells are more complex the prokaryotic cells?
ok..the answer your looking for is Eukaryotes

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.
Which are more complex eukaryot or virus?
Eukariyotic cells are very complex. Virus do not have cellular organization.

Difference between protein splicing and RNA splicing?
Protein splicing involves the excision of intervening peptide sequences called inteins from a precursor protein to produce the final functional protein, while RNA splicing involves removing introns and joining exons in pre-mRNA to form mature mRNA. Protein splicing occurs post-translationally in the protein after translation, while RNA splicing occurs co-transcriptionally during mRNA processing.
In eukaryotes control of gene expression is NOT by?
In eukaryotes, control of gene expression is not primarily achieved through simple transcriptional regulation alone; it also involves complex mechanisms such as chromatin remodeling, post-transcriptional modifications, and regulatory non-coding RNAs. Additionally, factors like alternative splicing and epigenetic modifications play crucial roles in fine-tuning gene expression. Thus, while transcriptional control is important, it is only one part of a multifaceted regulatory system.
