Final answer:
The percentage of protein functions that are unknown for discovered genes is currently unknown. The number of genes in an organism may be relatively low, but the number of different proteins that can be produced is much higher. The functions of many base pairs in the genome are still unclear.
Step-by-step explanation:
Estimates suggest that it is currently unknown what percentage of protein functions are unknown for discovered genes. However, it is important to note that while the number of genes in an organism may be relatively low (around 20,000 in humans), the number of different proteins that can be produced from these genes is much higher (up to 100,000 in humans). Additionally, the functions of many base pairs in the genome are still unclear.
