Do mitochondria have introns?
No, prokaryotes do not have introns, and therefore do not do RNA processing. However, eukaryotes do.
Why post-translational modification of protein does not occur in prokaryotes?
introns and exons are absent in prokaryotic rna hence processing not necessary
Why would a prokaryote fail to express a transplanted eukaryotic gene?
The biggest obstacle to expressing eukaryotic genes in prokaryotes is their structure. Eukaryotic genes have non-coding introns inserted between the coding exons, and these introns must be spliced out of the primary mRNA transcript before translation can proceed. The splicing is done by the spliceosome, a large, complex of RNA and protein. Prokaryotes do not have spliceosomes, thus eukaryotic genes would be transcribed with the introns intact, and translation by the ribosome would proceed on the primary mRNA transcript, resulting in non-functional proteins.
Do prokaryotes have nucleic acids?
Some have DNA, some have RNA, either way the answer is technically yes, althought neither is contained in a nucleus when it is found in a prokaryote
Why are introns copied and then removed from the RNA sequence?
Introns were copied and then removed from the RNA sequence because they were placeholders.
Do mitochondria have introns?
No, prokaryotes do not have introns, and therefore do not do RNA processing. However, eukaryotes do.
What is is the main difference between prokaryotes and eukaryotes?
Prokaryotes doesnt have a membrane its organelles pretty much just float around unlike eukaryotes it contains a membrane where the organelles are kept proteinsynthesis in prokaryotes- it doesnt not contain "noncoding" meaning it doesnt have introns
Why post-translational modification of protein does not occur in prokaryotes?
introns and exons are absent in prokaryotic rna hence processing not necessary

When was Introns - album - created?
Introns - album - was created on 2006-03-13.
How does the absence of a nuclear envelope in the prokaryotes prevent prokaryotes from controlling gene expression by modifying RNA after transcription?
In eukaryotes, mRNA is processed inside the nucleus before being shipped out into the cytoplasm for translation. Specifically, a strand of pre-mRNA (or immature mRNA) has a GTP cap added to its 5' end, a poly-adenine tail added to its 3' end, and it has its introns spliced out. Since prokaryotes don't have nuclear envelopes, they don't have an area to do this.
What is the common characteristics among eubacteria?
- unicellular prokaryotes - cell walls contain peptidoglycan - genes lack introns - reproduce asexually by binary - either autotrophic or heterotrophic - extremely diversified groups - certain types may be ancestors of mitochondria
How are eukaryotes and prokaryotes the different?
Prokaryotic cells do not have a nucleus and eukaryotic cells do. The main difference to remember is that everything in a eukaryotic cell is much larger and more complex than what would be fouind in a prokaryotic cell. Bacteria is made of prokaryotic cells. Plants and animals are made of eukaryotic cells. In addition to not having a nucleus (the main difference), prokaryotes also have circular DNA while eukaryotes have linear DNA. As such, prokaryotes do not have okazaki fragments formed during DNA replication. Eukaryote genes have introns and exons while prokaryotes do not, and eukaryotes have more "junk" DNA in general.
Do Prokaryotes have Prokaryotes?
yes prokaryotes have prokaryotes
Why are introns copied and then removed from the RNA sequence?
Introns were copied and then removed from the RNA sequence because they were placeholders.
What is the role of introns in gene regulation?
Introns are removed through RNA splicing. They don't play a role.
