Complete each sentence with the appropriate term or phrase. Some terms or phrases may be used once, more than once, or not at all exons In eukaryoptes mRNAs are frequently processed by capping, polyA addition, and splicing. In splicing introns are removed and exons ligated together to help create a mature mRNA. exon selectors For some mRNAs different forms of the same protein may be created by not using all of the possible in the final mature mRNA in a process that is referred to as alternative licin differential intron usage transcription factors Which parts of an pre-mRNA that are part of a mature mRNA is the result of the activity of The factors that control which parts of a pre- mRNA are used in the mature mRNA can either inhibit or enhance the recognition of splice sites by splicing factors splicing spliceosomes Reset

Explanation / Answer

1. For some mRNAs different forms of the same protein may be created by not using all the possible exons in the final mature mRNA in the process that is referred to as Alternate Splicing.

2. Part of the prem-RNA that are part of the mature mRNA is the result of the activity of Splicing Factors .

3. The factors which control part of the pre mRNA are used in the mature mRNA to recognise the splice site are Transcription factors.
