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.
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.
They are the more complex cells.
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.
Kingdom Protista contains complex single-celled organisms.
DNA is more complex in eukaryotes than in bacteria primarily due to the presence of multiple linear chromosomes, as opposed to the single circular chromosome found in bacteria. Eukaryotic DNA is tightly packed with histone proteins to form nucleosomes, allowing for greater organization and regulation of gene expression. Additionally, eukaryotic genomes contain introns and undergo processes like alternative splicing, further increasing their complexity. This structural and regulatory complexity enables more intricate cellular functions and greater adaptability in eukaryotic organisms.

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.
They are the more complex cells.
eukaryotes
Eukaryotes have a nucleus and other membrane-bound organelles, while prokaryotes do not. Eukaryotes are typically larger and more complex than prokaryotes.
ok..the answer your looking for is Eukaryotes

Eukariyotic cells are very complex. Virus do not have cellular organization.
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.
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.
