As you might know, introns DNA is something you can called 'Junk Fragments'.
It didn't contain any information. So its function as a protection to the coding fragment (exon...maybe i misspell it ).
DNA is subjected to many kind of mutation caused by chemical compounds or physical cause (gamma rays, for example). With Intron, when there's a mutation, there's a high probability that the one which subjected to the mutation is intron not exon. This way, eukaryote cells might survive from genetic mutation.
Human has a large number of intron in one gene. It cause human to survive from many kind of mutation.
What else can I help you with?
Do eukaryotes possess introns within their genetic material?
Yes, eukaryotes possess introns within their genetic material.
How is the DNA in a prokaryote different from the DNA In the eukaryote?
DNA in prokaryotes is circular and in the cell itself, while the DNA of eukaryotes is coiled and in the nucleus (organelle) of the cell.
In eukaryotes only exons are translated?
Correct. The mRNA transcibed from the DNA in the nucleus has both exons and introns; the introns are taken out and the exons are left in. The mended exons exit the nucleus and the introns stay in the nucleus. Only the exons are translated at the ribosomes. (In Eukaryotic cells only)
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 do eukaryotes have introns in their genetic material?
Eukaryotes have introns in their genetic material because they allow for alternative splicing, which enables a single gene to code for multiple proteins, increasing genetic diversity and complexity.
The difference between prokaryotic and eukaryotic DNA?
The difference is that eukaryotic DNA is organized into a well defined nucleus and prokaryotic DNA is not. An example of a prokaryote is bacteria (or a bacterium). Humans and fungi are eukaryotes. Prokaryotes also do not have introns (DNA that is not expressed), while Eukaryotes do.
Do eukaryotes possess introns within their genetic material?
Yes, eukaryotes possess introns within their genetic material.
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.
How is a bacterium's DNA different than eukaryote DNA?
In eukaryote cells DNA is inclosed in the nucleus of the cell. In prokaryote cells the DNA is diffused throughout the cell. DNA in bacteria is in a ring of a single chromosome that had no introns along the strand. DNA in eukaryotes is is strands that can be composed of chromosomes and many eukaryotes carry introns along the DNA. the amount of DNA present whether the DNA is housed in a nucleus or not whether the DNA is linear or circular all of the above are differences between prokaryotic and eukaryotic DNA
How is the DNA in a prokaryote different from the DNA In the eukaryote?
DNA in prokaryotes is circular and in the cell itself, while the DNA of eukaryotes is coiled and in the nucleus (organelle) of the cell.
Why prokaryotes do not have introns?
Prokaryotes do not have introns in their DNA because they lack a nucleus and have a simpler genetic organization compared to eukaryotes. Their genes are typically continuous sequences without interruptions, unlike eukaryotic genes which can have introns that need to be spliced out during gene expression.
In eukaryotes only exons are translated?
Correct. The mRNA transcibed from the DNA in the nucleus has both exons and introns; the introns are taken out and the exons are left in. The mended exons exit the nucleus and the introns stay in the nucleus. Only the exons are translated at the ribosomes. (In Eukaryotic cells only)
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.
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 do eukaryotes have introns in their genetic material?
Eukaryotes have introns in their genetic material because they allow for alternative splicing, which enables a single gene to code for multiple proteins, increasing genetic diversity and complexity.
Is the highest percentage of non coding DNA is found in bacteria or prokaryotes?
The highest percentage of non-coding DNA is found in eukaryotes, not in bacteria or prokaryotes. In eukaryotic organisms, non-coding DNA makes up a larger portion of the genome compared to coding DNA. This non-coding DNA includes regions such as introns, repetitive sequences, and regulatory elements.
Which of these statements does not describe introns?
Non-expressed
