Introns are segments of DNA that do not code for proteins and are removed during mRNA processing. They are formed during gene transcription when non-coding regions of pre-mRNA are included in the initial transcript. These introns are then spliced out by cellular machinery, leaving only the coding sequences to be translated into proteins.
What else can I help you with?
Which of these statements does not describe introns?
Non-expressed
Why do eukaryotic genes have introns but introns are absent from prokaryotic cells?
Look at the sheer amount of DNA that is contained into a eukaryotic gene (eukaryotes have more DNA to code for and so they can leave some of the DNA out, also look at the way the DNA is formed i.e. Eukaryotic genes are double stranded helixes and prokayrotic genes are a single strand of circular dna.
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?
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.
Why do the introns have to br removed?
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.
Does RNA have introns?
Yes, RNA does not have introns.
Do prokaryotic genes have introns?
No, prokaryotic genes do not have introns.
After the primary transcript mRNA has been formed what mediates the cutting of introns?
The process of removing introns from the pre-mRNA is mediated by a large complex called the spliceosome. The spliceosome recognizes the intron-exon boundaries and catalyzes the splicing reaction to remove the introns and join the exons together. This results in the formation of mature mRNA ready for translation.
Are there introns present in prokaryotes?
No, prokaryotes do not have introns in their genetic material.
Do prokaryotes have introns in their genetic material?
No, prokaryotes do not have introns in their genetic material.
Does bacteria have introns in their genetic material?
No, bacteria do not have introns in their genetic material.
Which of these statements does not describe introns?
Non-expressed
When was Introns - album - created?
Introns - album - was created on 2006-03-13.

Does mitochondrial DNA contain introns?
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.
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.
Can prokaryotes remove introns during gene expression?
No, prokaryotes do not remove introns during gene expression.
