Tries to explain
Genetic processes,
It soon finds out,
It's all about
Quite complicated messes:
DNA contains
Switching domains
In unexpected tracts,
And it's a pain
To ascertain
Where the switches act.
And furthermore.
It's quite a chore,
To find the switches paired
With genes, at all,
Which they control,
And to which tissue they adhere.
Some switches dwell
Only in cells
Where one they can always find,
And may relate
And regulate
Genes of another kind.
Hundreds of gents
Have years now spent
To try this maze unscramble,
Now they unfold
Their results
And that's just the preamble:
For it may take years
'Til it appears
The answer is perfected.
Which gene, which switch
Belong to each?
And how are they connected?
And even then,
The task begun,
To try to fight diseases
May take awhile,
With human trial
And hope to make life easier...
