Solution
The process you're referring to is known as "alternative RNA splicing". This is a process that can lead to a single gene coding for multiple proteins. In alternative splicing, certain exons of a gene may be included within or excluded from the final, processed messenger RNA (mRNA) produced from that gene. Consequently, the proteins translated from alternatively spliced mRNAs will contain differences in their amino acid sequence and, often, in their biological functions.
