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.

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 intron transcribed into the primary transcript?

No. The introns must be cut out of RNA before transcription. This is because a ribosome cannot read introns, and can only read axons. They are cut out and the axons are attached together to go through ribosome.


What are the unexpressed non-coding regions of eukaryotic genes called?

Unexpressed non-coding regions of eukaryotic genes are called introns. Introns are present in the initial RNA transcript but are removed during the process of RNA splicing, leaving only the expressed coding regions, called exons, in the mature mRNA.


Are most eukaryotic genes controlled individuallyor as groups?

indivdually


Why are there introns present in eukaryotic genes?

Introns are present in eukaryotic genes because they allow for alternative splicing, which enables a single gene to code for multiple proteins. This increases the diversity of proteins that can be produced from a single gene, allowing for greater complexity and regulation in eukaryotic organisms.


Where are the genes of a eukaryotic organism located?

The genes of a eukaryotic organism are located in the nucleus, within the DNA of its chromosomes. In eukaryotic cells, DNA is organized into multiple linear chromosomes, which contain the genetic information necessary for the organism's growth, development, and functioning.
