Question

Hint 1. How is a complete initiation complex formed? Drag the labels to their correct locations in the diagram to describe the roles of the various transcription factors in the formation of a complete initiation complex Reset Help part of initial committed complex TFIIA IIB added during formation of minimal initiation complex sa cosci.ccccccca RNA polymerase II added during formation of complete initiation complex Submit Request Answer

Answer 1

Ans (a) part of initial cornmitted complex (b) Added during formation of minimal initiation complex o added during formation of complete initiation complex 2 ③ capping can began as soon as RNA pol II has synthesized the first 20-30 nucleotides, at 5' end of transcript. a spleciosome pre - MRNA do not associate with the until transcription es complete

ans (3) TEID Binds) to TATA BOX ITFIATFOB 2. TFIF and YRNA pol I bind ТЕПЕ TRIH Bind Synthesis of 14 ore MRA begins/ at tl nucleotide (A5'cap is hadded to Pre mRNA spliceosomes complexes carry out intron Espiling A poly A tail is added to pre mRNA

Ans. O Exont lexon a intron 2 Exon 3 Explanation - mutation sequence in spricing intron a. signal in ③ 2 No mRNA produced Explanation - mutation in genes promotor sequence Exoni untrol/Exon-intron 2 Exon 3 ) Explandison – mutations in splicing sequences in both introns I entron 2 fron Exon 2 Exon 3 J - no mutation in any splicing, signal sequence.
