A primary RNA transcript may contain as many as 200,000 nucleotides (the average for human cells is 5,000). Yet mRNA in the cytoplasm averages only 1,000 nucleotides. All three types of RNA are processed in the nucleus of eukaryotes before they leave the nucleus. Enzymes add additional nucleotides and chemically modify or remove others. Mature RNA contains

What is the function of primary transcript?
The primary transcript, also known as pre-mRNA in eukaryotes, serves as the initial RNA copy synthesized from a DNA template during transcription. Its primary function is to carry the genetic information needed to produce proteins, which are essential for various cellular functions. Before becoming mature mRNA, the primary transcript undergoes several processing steps, including capping, polyadenylation, and splicing, to remove introns and join exons, ultimately preparing it for translation.
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.
What is the noncoding segement of a gene are cut out of an mRNA transcript?
The noncoding segments of a gene that are removed from an mRNA transcript during post-transcriptional processing are called introns. The remaining coding segments of the mRNA transcript, called exons, are then spliced together to form the mature mRNA that will be translated into a protein.
What the noncoding segment of a gene are cut out of an mRNA transcript while what are spliced?
The noncoding segments of a gene, called introns, are removed from the mRNA transcript during the process of splicing. The coding segments of a gene, called exons, are spliced together to form the mature mRNA molecule that can be translated into protein.
Where do lymphocytes mature so they can attack?
Lymphocytes mature in the primary lymphoid organs, which are the thymus for T cells and the bone marrow for B cells. Once they mature, they circulate in the bloodstream and lymphatic system to attack pathogens and foreign invaders.
What is the process of post-transcriptional modification?
Post-transcriptional modification is a process in cell biology by which, in eukararyotic cells, primary transcript RNA is converted into mature RNA. A notable example is the conversion of precursor messenger RNA into mature messenger RNA (mRNA), which includes splicing and occurs prior to protein synthesis. This process is vital for the correct translation of the genomes of eukaryotes as the human primary RNA transcript that is produced as a result of transcription contains both exons, which are coding sections of the primary RNA transcript.
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.

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 differences between university girls and high school girls?
They are just older and more mature.
What are the differences between children who watch cartoons and adults who watch cartoons?
No difference except one is mature.
Rna processing converts the RNA transcript into?
RNA processing converts the RNA transcript into mature mRNA by removing introns, adding a 5' cap and a 3' poly-A tail, and splicing exons together. This process ensures that the mature mRNA is ready for translation to produce proteins.
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 differences and similarities between the US and Europe how did they successfully concur areas?
The similarities between the US and Europe is that they have first world economies and have mature democracies.
What is the noncoding segement of a gene are cut out of an mRNA transcript?
The noncoding segments of a gene that are removed from an mRNA transcript during post-transcriptional processing are called introns. The remaining coding segments of the mRNA transcript, called exons, are then spliced together to form the mature mRNA that will be translated into a protein.
What percent of primary follicles a woman has at puberty will mature?
10%. About 40,000 primary follicles remain at puberty, and about 400 mature over a women's lifetime.
