Answer:
the precursor messenger RNA (pre-mRNA) of the L gene underwent alternative splicing, thereby producing three different mRNAs that have different lengths
Explanation:
In eukaryotic organisms, transcription produces a precursor mRNA (pre-mRNA), which is a non-processed RNA sequence that contains both non-coding regions (i.e., introns) and coding regions (i.e., exons). Subsequently, this pre-mRNA is converted into a mature messenger RNA (mRNA) by a process known as 'alternative splicing', where introns are removed and exons and exons spliced together to form a contiguous coding sequence. During alternative splicing, differential combinations of exons can be produced from the same gene, producing different mRNAs with different lengths.
The experimental results with the gel electrophoresis of the transcription of mRNA are due to the alternative splicing.
The genes are the codes that are enabled the formation of the DNA and RNA by expression. The transcription is the process of formation of mRNA from DNA template.
The mature mRNA is formed by the alternative splicing of the introns and the joining of exons for the functionalization. The process of alternative splicing results in the formation of the mRNA of multiple length.
The gel electrophoresis bands resulted have multiple length of mRNA. The results are the explanation for role of gene L in alternative splicing of mRNA.
