WebIn splicing, some sections of the RNA transcript (introns) are removed, and the remaining sections (exons) are stuck back together. Some genes can be alternatively spliced , leading to the production of different … WebApr 7, 2024 · However, this does not necessarily imply that splicing always follows the order in which introns are transcribed, as initially thought . Single-gene studies as well as more recent genome-wide analyses have confirmed that intron splicing order does not always occur linearly following the order of transcription ( 10–16 ). how big are timber rattlesnakes
