apicoplasts have been detected in all apicomplexan parasites studied, with the exception of Cryptosporidium

DNA viruses replicate in the nucleus by using host RNA polymerase for transcription and either host or viral DNA polymerase for replication (exception are poxviruses that replicate in the cytoplasm).

Most RNA viruses replicate in the cytoplasm—the immediate site of entry with the exception of influenza viruses and the retroviruses that replicate in the nucleus.

There are multiple grand truths

Structure Data 2014: Democratizing Artificial Intelligence with APIs
Apr 11, 2014
If you think Siri is smart, you haven’t seen anything yet. Hear how APIs are putting cutting-edge capabilities in deep learning, cognitive computing and artificial intelligence into the hands of developers everywhere.

00:40 cognition as a service
02:05 programatic computing
04:00 in congnitive systems, there is no absolute outcome
05:00 the grand truth
05:40 context is key. You can have multiple grand truths, depending on the situation. Vampires are real in certain contexts, but they’re not in others.

“… the data, which in the end would form the ‘grand truth’ that Watson would regard as baseline facts.”

There seems to be no term in the NN literature for the set of all cases that you want to be able to generalize to. Statisticians call this set the “population”. Tsypkin (1971) called it the “grand truth distribution,” but this term has never caught on.

the notion of context as a critical feature to understanding anything. Bateson (1979) was adamant in making the point that “without context, words and actions have no meaning at all” (p. 16).
Words and actions need to be situated in one or more relevant and meaningful contexts, in order to develop any degree of complex understandings.
