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.

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 non-coding introns from the primary mRNA transcript, and stiches the exons back together into the mature mRNA transcript.
What are eukaryotic genes composed of?
I belive is DNa.
Which organelle is the primary site of ATP synthesis in eukaryotic cells?
The mithochondria is the primary site of ATP synthesis in eukaryotic cells.
Name the sections of eukaryotic genes that are transcribed and translated?
introns and exons
Are both intron and exon regions are transcribed into the primary transcript?
yes
Why would a prokaryote fail to express a transplanted eukaryotic gene?
The biggest obstacle to expressing eukaryotic genes in prokaryotes is their structure. Eukaryotic genes have non-coding introns inserted between the coding exons, and these introns must be spliced out of the primary mRNA transcript before translation can proceed. The splicing is done by the spliceosome, a large, complex of RNA and protein. Prokaryotes do not have spliceosomes, thus eukaryotic genes would be transcribed with the introns intact, and translation by the ribosome would proceed on the primary mRNA transcript, resulting in non-functional proteins.
Do eukaryotic cells have genes?
All cells have genes

What are the final products of proteins?
In prokaryotic cells, mRNA is directly produced. In eukaryotic cells, the first product is called the primary transcript.

The chromosomes of eukaryotic cells have more?
genes
Are most eukaryotic genes controlled individuallyor as groups?
indivdually
Which organelle is the primary site of ATP synthesis in eukaryotic cells?
The mithochondria is the primary site of ATP synthesis in eukaryotic cells.
Name the sections of eukaryotic genes that are transcribed and translated?
introns and exons
Why do eukaryotic genes have introns but introns are absent from prokaryotic cells?
Look at the sheer amount of DNA that is contained into a eukaryotic gene (eukaryotes have more DNA to code for and so they can leave some of the DNA out, also look at the way the DNA is formed i.e. Eukaryotic genes are double stranded helixes and prokayrotic genes are a single strand of circular dna.
In which organelle is DNA kept and RNA transcript?
The nucleus stores DNA and is where RNA transcription occurs.
Are both intron and exon regions are transcribed into the primary transcript?
yes
