These genes are typical in eukaryotic organisms. Here’s a detailed look at split genes and the mechanisms involved in their processing: Structure of Split Genes Exons: Coding sequences that are transcribed into mRNA and translated into protein. Introns: Non-coding sequences that are transcribed into RNA but are spliced out during RNA processing. Transcription and RNA Processing 1. Transcription The entire gene, including both exons and introns, is transcribed into a precursor mRNA (pre-mRNA). 2. RNA Processing Capping: A 7-methylguanosine cap is added to the 5' end of the pre-mRNA, protecting it from degradation and assisting in ribosome binding during translation. Polyadenylation: A poly-A tail, consisting of a chain of adenine nucleotides, is added to the 3' end of the pre-mRNA, aiding in stability and export from the nucleus. Splicing: Introns are removed, and exons are joined together to form a continuous coding sequence. This process involves several key components: Spliceosome: A complex of small nuclear RNAs (snRNAs) and protein factors that facilitates the splicing process. Branch Point: A specific adenine nucleotide within the intron that plays a critical role in the splicing mechanism. Splice Sites: Conserved sequences at the exon-intron boundaries where splicing occurs, typically characterized by GU at the 5' end (5' splice site) and AG at the 3' end (3' splice site) of the intron. #molecularbasisofinheritanceoneshot #molecularbasisofinheritancencert #molecularbasisofinheritanceclass12 #class12biologychapter6 #molecularbasisofinheritancencertsolutions #ncertmolecularbasisofinheritance #molecularbasisofinheritanceclass12ncert #molecularbasisofinheritanceclass12biology #molecularbasisofinheritanceclass12ncertsolutions #class12biologymolecularbasisofinheritance #class12biologychaptermolecularbasisofinheritance #molecularbasisofinheritanceclass12questions #biologymolecularbasisofinheritanceclass12 #Class12Biology #Class11Biology #NEETBiologyExam #NEET2023 #NEETBiologyOneShot #BiologyOneShot #NEET2023Biology #NEETBiologyPreparation #NEET2023BiologyExam #NEET2023BiologyPreparation #NEETBiology This video includes :- -- Molecular Basis of Inheritance Part 27 -- Split gene and splicing ✔ Time Stamps :- 00:00 Molecular Basis of Inheritance Part 27 00:37 Split gene and splicing NEET Preparation Videos Playlist Reproduction in Flowering Plant :-    • SEXUAL REPRODUCTION  IN ANGIOSPERM - PART ...   Human Reproduction :-    • HUMAN REPRODUCTION -CLASS -12th - PART - 1...   Human Reproduction NCERT DISCUSSION :-    • HUMAN REPRODUCTION-NCERT DISCUSSION-Part-1   Reproductive Health :-    • REPRODUCTIVE HEALTH - PART -1- INTRODUCTION.   Principles of Inheritance and Variation :-    • Introduction To Mendelian Genetics | Princ...
