What are the difference between exons and introns?
The difference between exons and introns is that exons are codes of proteins, while introns are not involved with the coding for proteins. Read More
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) Read More
What is the difference between introns and exons?
Exons are the DNA sequences that code for proteins. Introns are involved however they dont carry the genetic information that exons carry Read More
What happens to the introns and exons during transcription?
During transcription, the entire gene is copied into a pre-mRNA, which includes exons and introns. Read More
Mutations in introns are less likely to affect phenotype then mutation in exons?
mutation in exons are less likely to affect phenotype then mutation in introns because mutaion in exons are silent mutation Read More
How do exons and introns relate to mRNA?
Exons and introns are part of the mRNA. During transcription inside the nucleus, introns are removed from the mRNA because they are not coded to make a protein. Exons are then joined together because that is the part required for translation. After exons are joined together and introns are taken out, the mRNA is then attached to the poly(A) tail in the 3' end and 5' cap in the 5' end. The finished mRNA is… Read More
What is the difference between exons and introns?
Exons are the DNA sequences that code for proteins. Introns are involved however they dont carry the genetic information that exons carry, the variation provides for revolutionary flexibility allowing cells to shuffle exons between genes to make new ones. A great way to remember which is which is Exons (sounds like Executives, like in a business) have the information and introns (sounds like the interns of a business) dont know anything; exons and inrons, executives… Read More
What are introns and exons?
Intronsare intervening sequence of DNA; does NOT code for a protein. Exons are expressed squence of DNA; codes for a protein. Read More
What happens to exons and introns after the mRNA in transcribed in the nucleus but before its translated in the ribosome?
After transcription, the mRNA is processed by the spliceosome, which splices out the introns (because introns are not part of the coding sequences for protein), and "stitches" the exons together to form the final transcript that is sent to the ribosome for translation. Read More

How do introns and exons relate to RNA splicing?
Before the RNA leaves the nucleus, the introns are removed and the exons are joined together, producing an mRNA molecule with a continuous coding sequence. This process is called RNA splicing. Read More
Are introns or exons on prokaryotic mRNA?
Exons are part of both prokaryotic and eukaryotic. Introns are rarely present in the domain bacteria (common bacteria) while introns are present in some genes in domain archaea ("ancient" bacteria). Both are considered prokaryotic. No, they are only present on tRNA and rRNA. Read More
Is there any relation between the number of introns and exons in a gene?
For one; there was a Time when there was no such thing as an intron, all genetic material was expressed. Having said that, as Time went by, the ratio of [expressed] exons to [suppressed] introns shrank. Read More
Nucleotide segments that code for amino acids?
this is the correct answer i promise exons It's right ^^ It's not introns because introns do not code. Read More
Distinguish between pre-mRNA and mRNA?
pre-mrna has introns and exon as for mrna it removes the introns but remain exons Read More
What is the function of the spliceosome?
In eukaryotic organisms, genes consist of exons and introns. Exons are regions that are transcribed into mature messenger RNA, and eventually translated into protein. Interspersed within the exons are introns, regions of non-coding DNA. Introns must be removed from the initial transcript of mRNA before the final mature transcript is sent to the ribosome for translation into protein. This removal is done in a coimplex protein structure called the spliceosome. The spliceosome splices out the… Read More
After introns have been cut out of RNA molecules the remaining piece is called what?
exons Read More
What is spliced together to make the final mRNA?
Exons, after the introns have been cleaved. Read More
Do exons contain noncoding DNA?
no because the introns have no function in protein synthesis Read More
Does a cDNA library have only exons?
A cDNA library consists only of genes that are expressed, hence they do contain only exons. They contain no introns. Read More
How does a primary transcript differ from a functional mRNA in a eukaryotic cell?
the primary transcript usually has a exons and introns which need to undergo splicing to remove the introns and re-splicing to join the exons ..after this process the resulting mRNA is a mature mRNA. Read More
Why do scientists think that introns and exons contribute to evolutionary flexibility?
many biologist think that this organization of genes add evolutionary felixablity . Each Econ protein adds a different part of a protein by having introns and Exons fellas can occasionally shuffle exons between genes and make new ones . Read More
Do introns and exons play any role in protein synthesis?
Exons are the coding regions which bear codons, each codon representing one amino acid. Thus exons are directly responsible for the amino acid sequence of the proteins. Introns are intervening sequences and bear no coding regions and cannot influence the protein sequence. Read More
Introns are significant to biological evolution because?
because their presence allows exons to be shuffled. Read More
What are exons and introns?
Exons are sequences on the primary transcript, or pre-mRNA (or the DNA sequence from which it is transcribed), that remain in the RNA after RNA processing. Introns are sequences on the primary transcript, or pre-mRNA (or the DNA sequence from which it is transcribed), that are removed from the RNA after RNA processing Read More
What is the mRNA sequence splicing?
Eukaryotic genes have regions called "introns" and "exons". Exons code for polypeptides (often specific domains or motifs), while introns don't code for anything (that we know of) and are removed. mRNA splicing is the process where an mRNA molecule is cut up (usually by the "spliceosome") to remove the introns from an mRNA message. This is advantageous for us eukaryotes because we can recombine exons in different orders, and even combine exons from different genes… Read More
Genes that are transcribed are called?
Genes that get transcribed is called structural gene. It is also known as the amino acid coding region. Our genome is made up of alternating introns and exons. Introns are the non-coding region the the genome whereas exons are the coding sequences. Read More

What is the region of DNA within a gene not translated into protein?
There are several regions in a gene that are not translated. Promotor and enhancer regions as well as start sites such as the TATA box are not transcribed. Introns and Exons are both transcribed but introns are spliced out leaving only exons to be translated into proteins. Read More
What do you call a short piece of DNA that codes for a certain protein?
DNA does not make proteins directly. Rather, the DNA is the mother-of-all recipes that specialized transcription proteins (tRNA) read to make messenger RNA (mRNA). mRNA is the specific recipe to make specific proteins. The specific code of DNA are made of regions called introns and exons. Exons are what the gene has coded for and introns are "spacers". I remember exons are exactly what is needed and introns are intervening sequences. Read More
What is mRNA splicing?
In molecular biology, splicing is a modification of an RNA after transcription, in which introns are removed and exons are joined. Read More
Why does RNA processing does not occur in prokaryotes?
introns and exons are absent in prokaryotic rna hence processing not necessary Read More

Exons are what are expressed while introns are spliced out. Read More
What is the difference between pre-mRNA and mRNA?
The first (primary) transcript from a protein coding gene is often called a pre-mRNA and contains both introns and exons. Pre-mRNA requires splicing (removal) of introns to produce the final mRNA molecule containing only exons Read More
The part of mRNA that is removed?
During the transcription, when the mRNA is being processed, the introns are removed and the exons are connected together. Read More
What is the difference between an intron and exon?

In eukaryotes what are segments of genes that do not code for a protein?
These are known as introns. There are more than one type. You can always tell an intron from an exon by the fact that exons are the [reassembled] genes that are, after the introns are excised, expressed. Read More
What is meant by introns?
Introns are a part of your genetics that are edited out when making mRNA after transcription. The opposite are exons, which are the "keeper" parts. A chunk of DNA, called a gene is read and copied (like a photocopy) into a disposable piece called mRNA. This process is called Transcription. However, the mRNA "photocopy" isn't ready for the next step, called Translation. It needs editing. Pieces are chopped out of it and the remaining pieces… Read More
