Detailed explanation-1: -Abstract. After transcription of a eukaryotic pre-mRNA, its introns are removed by the spliceosome, joining exons for translation.
Detailed explanation-2: -Introns are nucleotide sequences in DNA and RNA that do not directly code for proteins, and are removed during the precursor messenger RNA (pre-mRNA) stage of maturation of mRNA by RNA splicing.
Detailed explanation-3: -An intron is a region that resides within a gene but does not remain in the final mature mRNA molecule following transcription of that gene and does not code for amino acids that make up the protein encoded by that gene. Most protein-coding genes in the human genome consist of exons and introns.
Detailed explanation-4: -In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.
