According to the text, how would sequencing the entire genome of an organism primarily help scientists understand how that organism functioned?
A: By determining the specific amino acid sequence of every protein produced by the organism, directly revealing protein function.
B: By providing the complete set of an organism's DNA, which includes all genes and their sequences, thus offering a blueprint for its genetic makeup and potential functions.
C: By identifying only the non-coding regions of the DNA, as these regions are solely responsible for regulating all cellular processes.
D: By allowing scientists to physically manipulate individual genes to observe immediate phenotypic changes in real-time.
Explanation
The text states, 'To fully understand the genetic functioning of a living organism, the entire sequence of the full complement of DNA, the organism’s genome, would be most enlightening.' This implies that having the complete genomic sequence provides the fundamental information needed to understand its functions.
