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 part of a DNA molecule contains the instruction of making chromosome packaging proteins?
In prokaryotes the genes directly specify proteins.In eukaryotes the exons within the genes specify proteins, the introns within the genes are noncoding DNA that alternate with exons and are spliced out in the process of transcription to messenger RNA.
Regulatory proteins in eukaryotes that are involved in controlling the onset of transcription are called?
operators.....
Where does translocation in eukaryotes occur?
In the Endoplasmic Reticulum (ER). It must leave the nucleus first after transcription.
What area of a gene carries the code used to make a protein?
The coding region. In eukaryotes this is often divided into a number of discreet regions of DNA called exons.
Where does trancription occur?
Transcription is the process of formation of RNA. It takes place in nucleus in eukaryotes and in nucleoid in bacteria or prokaryotes .
Describe how RNA is processed in eukaryotes What is the purpose of each step?
Introns are cut out, and the resulting exons are spliced together.Exons are cut out, and the introns are spliced together.Introns are cut out and spliced together at the end of the mRNA.Exons are cut out and transported to smooth endoplasmic reticulum.Introns are cut out and transported to the ribosomes

Active DNA transcription in eukaryotes occurs?
Transcription takes place in the nucleus of eukaryotic cells.
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.
Why are most mutations in eukaryotes recessive?
they like to be so they are
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)
Where does transcription occurs in eukaryotes?
in the cytoplasm
What are the sense portions of a pre-mRNA strand made in transcription called?
Exons
The process of joining exons together to form an mRNA molecule is called?
Transcription
What are three differences between transcription in prokaryotes and transcription in eukaryotes?
different places
What kind of organisms use transcription factors?
Eukaryotes
The TATA box in eukaryotes helps to ensure transcription true or false?
True, the TATA box helps ensure transcription in prokaryotes and eukaryotes. It is found in the promoter region of genes.
