Cloning the Bard

[Oscar]

Inspector Dudley 'Dud' Foleyowes of the Literary Integrity Enforcement Dept of Scotland Yard showed me two pieces of paper.
They each contained lines which were wildly different but somehow strangely similar.

He allowed me a moment to study them before he carried on:
'The first passage I'm sure you recognise as from 'Romeo and Juliet' and we're pretty sure the second one is the work of Bill Wagglepike, the notorious forger of things Shakespearean. Our informant tells us that he managed to lay his hands on a preserved piece of fingernail cut from the Bard's writing hand and has used it to power a diabolical literature-cloning machine: he simply inserts some original text, flicks a switch and out comes a cloned 'copy'. The beauty from Wagglepike's point of view is that it's not an exact copy but something that well-established tests will 'prove' is a hitherto unknown work by W.S.'

I looked at the two passages and shook my head.
'Are you sure the second piece is derived from Romeo and Juliet? It seems rather ... weird.'

'Our own scientific tests show that it has to be a clone with very little room for doubt. If we don't nail him soon he'll flood the market with horrific ersatz Shakespeare plays that private collectors will pay anything to get their hands on!'

I took the second piece of paper from his hand and reproduce it here as a warning:

How cool! Shall this little blender send me to Mars?
It will start and stop like our son!
Also shall my nan do her very nut within
where a breadstick and pasty lie still,
flat fleshly hard as it arrests all blankly;


I trust you recognise the passage the inspector thinks inspired it and why he is convinced it must be a clone?

I'll kick this off with what seems to me to be the obvious passage from Romeo and Juliet. I'm wondering if Cloning indicates to use a process like crossover? There seems to be fewer similarities the further you go. Anagram is mostly ruled out by the lack of a J anywhere in the new text.

[Oscar]

I can confirm that that is the passage the Inspector believes to have been cloned. As a hint to how the cloning device might work the Inspector studied molecular biochemistry and has what Zag might term a 'loosey-goosey' approach to detection.

[Zag]

I had even considered that passage, being one of the few Shakespearean bits I know and the first phrase kind of fitting, but I still don't see the rest of the connection. L'lanmal, care to drop a hint for the slower ones among us?

[Oscar]

Lest anyone spend too much time working on some rigid analytical approach I'd like to emphasise the (attempted) light-hearted tone of the puzzle text.

[L'lanmal]

I didn't have anything definitive. Just a lot of common letters, and a couple of rhymes (blankly / than she) and a homophone (sun / son). I am imagining the cloning has something to do with either transcription errors (changing many letters, but leaving others in place) or crossover (taking letters from one string into another).

[L'lanmal]

AND, or at least A, N, & D, in all lines?

[L'lanmal]

It is a clone because (spoiler) All the "DNA" matches!.

[Oscar]

You got it, L'lanmal! I understand that [molecular cloning results in identical DNA... according to Inspector Foleyowes the other letters in the Shakespeare fragment were randomly replaced ]

[Jack_Ian]

I realise this is not part of the puzzle, but nevertheless…
I get the Bill Wagglepike reference, but Inspector Dudley 'Dud' Foleyowes still escapes me.

[Oscar]

'Dud' as in 'shoddy', 'Foleyowes' as a homophone for (Shakespeare's) folios...

[Jack_Ian]

Wow! Can't believe I missed that. Seems so obvious now.
