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.

Why are most mutations in eukaryotes recessive?
they like to be so they are
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.
Name the sections of eukaryotic genes that are transcribed and translated?
introns and exons
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.
Gene expression might be altered at the level of post-transcriptional processing in eukaryotes rather than prokaryotes because of what?
Eukaryotic exons may be spliced in alternative patterns

Which regions of DNA are transcribed to RNA and then translated to form a polypeptide?
Exons

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.

Eukaryotic exons may be spliced in alternative patterns
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.
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.
What is the Mrna sequence?
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 to generate many proteins from a smaller number of genes.

Do eukaryotes have mitochondrins?
Of course they have.They are only in eukaryotes
