Yes they are. Exons are expressed.
Non-expressed
Introns were copied and then removed from the RNA sequence because they were placeholders.
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.
Introns are the non-coding parts of the gene. If you didn't remove introns, the wrong protein may be produced because they allow more than one protein to be produced from a single gene.
Mutations in introns are less likely to affect phenotype because introns are not translated into protein, unlike exons which contain coding regions for proteins. Introns are involved in regulation of gene expression through processes such as alternative splicing, but mutations within introns typically have a more subtle impact on gene expression compared to mutations in coding regions (exons).
Yes, RNA does not have introns.
No, prokaryotic genes do not have introns.
No, prokaryotes do not have introns in their genetic material.
No, prokaryotes do not have introns in their genetic material.
No, bacteria do not have introns in their genetic material.
Introns - album - was created on 2006-03-13.
Non-expressed
Yes, mitochondrial DNA does not contain introns. Mitochondrial DNA is a circular molecule that lacks introns, which are non-coding regions found in nuclear DNA.
Introns were copied and then removed from the RNA sequence because they were placeholders.
No, prokaryotes do not remove introns during gene expression.
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.
Yes, eukaryotes possess introns within their genetic material.
