Not long ago,it was believed that a count of the number of protein-coding genes would provide a count of the number of proteins produced in any given eukaryotic species.This is incorrect,largely due to the discovery of widespread _____.
A)chromatin condensation control
B)transcriptional control
C)alternative splicing
D)translational control

Question

Quizplus · Accepted Answer

Alternative splicing is the process by which different combinations of exons within a single gene can be spliced together to produce multiple distinct mRNA sequences from the same gene. This allows for the production of multiple protein isoforms from a single gene, greatly increasing the potential diversity of the proteome beyond what would be expected based solely on the number of protein-coding genes in a genome. Therefore, the discovery of widespread alternative splicing has led to the realization that the number of protein-coding genes is not necessarily proportional to the number of proteins produced in a given eukaryotic species.
