Question

A transversion somewhere within gene B in a laboratory plant results in the production of a mutant mRNA that is much longer than the wild type. This transversion is most likely located

- downstream of the STOP codon, in the last exon of gene B.
- in an intron of gene B away from the splice sites.
- in the open reading frame of gene B.
- within a splice site of gene B.
- within the promoter of gene B.

Answer 1

Within a splice site of gene B

Step-by-step explanation:

RNA splicing is a process that is taking place in biology. It is a process of transferring newly made up of mRNA into a mature mRNA. In the splicing process, the introns go out and exons come in and joined together. The splicing gas has been taken immediately after transcription. Splicing occurs in different methods that are dependent on the splicing process of introns and the catalyst requires the splicing. Self-splicing occurred very rarely.

There are given three self-splicing intron:

• Group I

• Group II

• Group III
