What is the primary transcript of eukaryotic genes?
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.
The principal problem with inserting an unmodified mammalian gene into the bacterial chromosome and then getting that gene expressed is that?
bacteria cannot remove eukaryotic introns; bacterial dna does not contain introns like eukaryotic genes do so they had to be removed before being added to the plasmid.
Why must introns be removed while the exons remain in the mRNA?
Introns are non-translated sections of a gene, i.e. they are not made into protein. The gene is stored in the chromosomes as DNA. When the corresponding protein is needed, the DNA is copied (transcribed) by RNA polymerase making a complementary copy of the gene made of RNA. This is then processed to remove the introns (the non-coding parts of the gene). It was long thought these introns hasdno use. However, there is evidence that they have a role in the processing of the RNA. In addition, introns allow more than one protein to be produced from a single gene. The RNA with the introns removed is now the messenger RNA (mRNA) which is transported out of the nucleus into the cytoplasm, where it is read by the ribosome, which produces the coded protein.

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 to generate many proteins from a smaller number of genes.
Why is the RNA in the cytosol much smaller than the RNA in the nucleus?
In the nucleus, RNA is transcribed from the entire gene. The genes contain both introns and exons. Only the exons contain the coding information for the protein. After transcription these long RNAs (called hnRNA) are processed to remove the introns. After adding a poly A tail, and a cap on the 5' end, the now much smaller RNA is exported into the cytosol where it can be translated.

Why do the introns have to br removed?
Introns are the non-coding parts of the gene. If you didn't remove introns, the wrong protein may be produced because they allow more than one protein to be produced from a single gene.
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.

most likely it is the high mount rear brake light. Open hatch and you will see where to remove the screw to access the bulb.

How do you remove someone else's name from a bank account?
A person will need to check the bank's requirements in order to remove someone from a bank account. The primary person will need to contact the bank and will most likely have to go to the main bank branch.
