What else can I help you with?
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.
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.
Which organelle is the primary site of ATP synthesis in eukaryotic cells?
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.
Are both intron and exon regions are transcribed into the primary transcript?
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.
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.
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.
The chromosomes of eukaryotic cells have more?
genes
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.
What organelle contains genes?
carbonbb
What do the chromosomes of eukaryotic cell have more of than those of a prokaryotic cell?
Genes
In eukaryotic cells the mRNA is processed and migrates from the to the .?
The mRNA produced by transcription is similar to a rough cut of a film that needs a bit of editing. A specialized nucleotide is added to the beggining of each mRNA molecule, which forms a cap. It helps the mRNA starand bind to a ribosome and prevents the strand from being broken down to fast. The end of the mRNA molecule gets a string of A nucleotides, called the tail, that helps the mRNA molecule exit the nucleus.
