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.

What else can I help you with?
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.
In a eukaryote what is a segment of a gene that codes for a protein?
A segment of a gene that codes for a protein is called an exon. Exons are the parts of a gene that are ultimately expressed as proteins after being transcribed and translated. They are interspersed with non-coding regions called introns.
What happens to the introns and exons during transcription?
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.
Name the sections of eukaryotic genes that are transcribed and translated?
Eukaryotic genes are comprised of several sections, with the two main ones being exons, which are transcribed and translated to form proteins, and introns, which are transcribed but not translated and are usually spliced out during pre-mRNA processing. Promoters and enhancers are other sections involved in regulating gene expression.
Intervening DNA sequences that are transcribed and then removed from the final mrna is called?
Introns are intervening DNA sequences that are transcribed but then removed from the pre-mRNA during RNA processing. This process, called splicing, results in the mature mRNA containing only the exons which are the coding sequences that are retained and translated into proteins.
Are Exons Cut After Transcription In Eukaryotes?
No. The Ex in Exon refers to Expression.Introns are nucleotide sequences within genes that are removed by RNA splicing to generate the final mature RNA product of a gene.
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.
What are the pieces of a split gene called in eukaryotes?
exons - good parts of gene that code for amino acids introns- "junk DNA" that do not code for amino acids of a protein ( before leaving the nucles mRNA must have these removed, then it can travel into the cytoplasm)
Which regions of DNA are transcribed to RNA and then translated to form a polypeptide?
The regions of DNA that are transcribed to RNA are called exons. These exons will then be spliced together to form messenger RNA (mRNA), which will be translated into a polypeptide. Introns are the non-coding regions of DNA that are removed during the splicing process and are not translated into protein.
In a eukaryote what is a segment of a gene that codes for a protein?
A segment of a gene that codes for a protein is called an exon. Exons are the parts of a gene that are ultimately expressed as proteins after being transcribed and translated. They are interspersed with non-coding regions called introns.
What happens to the introns and exons during transcription?
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.
What are RNA segments joined to one another by spliceosomes?
RNA segments joined together by spliceosomes are called exons. Spliceosomes remove introns from pre-mRNA molecules and ligate exons together to produce a mature mRNA transcript that can be translated into a protein. This process is known as RNA splicing.
Why are exons important?
Exons are important because they contain the genetic information needed to code for proteins. During gene expression, exons are transcribed into mRNA which is then translated into proteins. Mutations or changes in exons can alter the sequence of amino acids in a protein, leading to functional changes or diseases.
What are the codes for proteins is it exons or introns?
The codes for proteins are found in the exons of a gene. Exons are the coding regions of a gene that are transcribed into mRNA and translated into proteins. Introns, on the other hand, are non-coding regions that are spliced out during RNA processing and do not contribute to protein synthesis.
What portion of an eukaryotic gene is not spliced out?
In a eukaryotic gene, the portion that is not spliced out is the exons. Exons are the coding sequences that remain in the mature mRNA after the introns, which are non-coding regions, have been removed during the splicing process. These exons are then translated into proteins, while the introns are discarded.
What are the introns and exons?
An intron is a DNA region within a gene that is not translated into protein. After intron splicing (ie. removal), the mRNA consists only of exon derived sequences, which are translated into a protein.
Name the sections of eukaryotic genes that are transcribed and translated?
Eukaryotic genes are comprised of several sections, with the two main ones being exons, which are transcribed and translated to form proteins, and introns, which are transcribed but not translated and are usually spliced out during pre-mRNA processing. Promoters and enhancers are other sections involved in regulating gene expression.
