Functional coupling of transcription and splicing

Area of Science:

• Molecular Biology
• Genetics
• Gene Expression Regulation

Background:

• Alternative splicing of precursor messenger RNA (pre-mRNA) is crucial for protein diversity.
• Transcription and splicing are increasingly recognized as physically and functionally coupled processes.
• This coupling is vital for the precise regulation of gene expression.

Purpose of the Study:
