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.
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.
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.
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.
The primary site of ATP synthesis in eukaryotic cells is the mitochondrion. Mitochondria generate ATP through a process called oxidative phosphorylation, which occurs in the inner mitochondrial membrane.
Yes, both intron and exon regions are transcribed into the primary transcript during transcription. However, only the exons are retained in the processed mRNA after introns are removed through the process of splicing.
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.
All cells have genes
In prokaryotic cells, mRNA is directly produced. In eukaryotic cells, the first product is called 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.

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.

Eukaryotic genes are segments of DNA found within eukaryotic organisms, which include animals, plants, fungi, and protists. These genes contain the instructions for synthesizing proteins and are organized into chromosomes within a defined nucleus. Eukaryotic genes often include regulatory elements that control their expression, allowing for complex patterns of gene regulation and expression in response to environmental and developmental cues. Additionally, eukaryotic genes may undergo processes such as splicing, where introns are removed and exons are joined, contributing to the diversity of proteins produced.
