NEET BIOLOGY

Detailed explanation-1: -The correct option is A Splicing. Splicing is the process of removal of intron sequences and joining the exon sequences.

Detailed explanation-2: -Final answer: Removal of introns and joining the exons in a defined order in a transcription unit is called splicing.

Detailed explanation-3: -Listen to pronunciation. (SPLY-sing) The process by which introns, the noncoding regions of genes, are excised out of the primary messenger RNA transcript, and the exons (i.e., coding regions) are joined together to generate mature messenger RNA.

Detailed explanation-4: -One of the steps in this processing, called RNA splicing, involves the removal or “splicing out” of certain sequences referred to as intervening sequences, or introns. The final mRNA thus consists of the remaining sequences, called exons, which are connected to one another through the splicing process.

Detailed explanation-5: -As DNA is transcribed into RNA it needs to be edited to remove non-coding regions, or introns, shown in green. This editing process is called splicing, which involves removing the introns, leaving only the yellow, protein-coding regions, called exons.
