RNA splicing
Transcription.During transcription the base sequence (genetic code) of part (a gene) of one strand of DNA is copied onto a strand of RNA as the RNA is synthesized.

Transcription
Transcription (DNA -> RNA) happens in the nucleus where RNA polymerase makes single-stranded RNA from a template DNA strand.

Yes, RNA does not have introns.
During the process of RNA splicing, introns are spliced out, while exons are joined together to form the mature mRNA molecule.
Before the RNA leaves the nucleus, the introns are removed and the exons are joined together, producing an mRNA molecule with a continuous coding sequence. This process is called RNA splicing.
Excision to make the completed mRNA involves the removal of introns from the pre-mRNA molecule through a process called splicing. This process is carried out by the spliceosome, a complex of RNA and protein molecules that recognize specific sequences at the boundaries of introns. The spliceosome removes the introns and joins together the remaining exons to form the mature mRNA molecule.
In the nucleus, RNA is transcribed from the entire gene. The genes contain both introns and exons. Only the exons contain the coding information for the protein. After transcription these long RNAs (called hnRNA) are processed to remove the introns. After adding a poly A tail, and a cap on the 5' end, the now much smaller RNA is exported into the cytosol where it can be translated.
Introns were copied and then removed from the RNA sequence because they were placeholders.
The intervening sequences of RNA molecules that are cut out before the messenger RNA leaves the nucleus are called introns. These introns are non-coding sequences that are spliced out of the pre-mRNA during the process of RNA splicing, leaving only the exons to form the mature mRNA that is then transported to the cytoplasm for translation.
The regions of RNA that code for proteins are called exons. Exons are the segments of RNA that are retained after the splicing process, where non-coding regions known as introns are removed. Together, exons are translated into amino acids to form proteins during the process of translation.
Internal noncoding regions of RNA are called introns. They are segments of an RNA molecule that interrupt the sequence of genes.
removal of introns and joining of exons in pre-mRNA to produce mature mRNA that can be translated into a protein. This process is carried out by a complex called the spliceosome, which recognizes specific sequences at the ends of introns to facilitate their removal and joining of exons. RNA splicing plays a crucial role in generating protein diversity and regulating gene expression.
Many RNA molecules from eukaryotic genes have sections called introns that are removed through a process called splicing before the mature RNA molecule is produced. The sections that remain in the final RNA molecule are called exons.
