Question

The human protein coding gene frt has three exons. A mutation at the splice junction between the second exon and first intron leads to an inability to remove a DNA segment during splicing. Which of the following is describes the most likely outcome(s) of this mutation: O termination of transcription within the coding sequence of the second intron O termination of transcription before the coding sequence of the second exon termination of translation within the coding sequence of the second exon termination of translation within the coding sequence of the second intron O termination of translation before the coding sequence of the second exon

Answer 1

Exon 1 Intron 1 Exon 2 Introna Exon3 ? Mutation at to Hemone C all to going offect first are this spice sile lead to inability DNA kugment during splicing. - first this splicing happen once the transcuiption is Complete this mutation is not transcription hence two options (talking about transcription) incorrect. transcription mRNA is formed that takes pauts in franslation mutation going translation. As this modation is soewing between Inloon 1 and Exon 2 it lead termination before the codi Exon of Sequence Here mutation is oce wring between Intron 1 & Exon 2 won't be obseg, ved beyond Inbon 1 (04 wrong. After this to affect hill to coding ko Secon is correct so option 5th its Effect mutation site) 4 are option 2 and the
