Another 'not just... but...' question but apparently different one
Please check out this thread about 'not just... but...' because it is closely related with this question.
The passage below is from ‘the Blank Slate’ by Steven Pinker.
http://evolbiol.ru/blankslate/blankslate.htm There are two other reasons why the complexity of the genome is not reflected in the number of genes it contains. One is that a given gene can produce
not just one protein
but several. A gene is typically broken into stretches of DNA that code for fragments of protein (exons) separated by stretches of DNA that don't (introns), a bit like a magazine article interrupted by ads. The segments of a gene can then be spliced together in multiple ways.
The 'not just... but...' in this passage seems different to the case of the former thread.
It would rather be replaced by 'not... but...,' not 'not only... but also...'
Am I right?
Regards.
