Question
Explain how the use of alternative promoters and alternative polyadenylation signals produces mRNAs with different $5^{\prime}-$ and $3^{\prime}$ -ends.
Step 1
Alternative promoters: A promoter is a DNA sequence that initiates the transcription of a particular gene. Some genes have multiple promoters, which can be used to produce different mRNA transcripts with different 5'-ends. When an alternative promoter is used, the Show more…
