Jabberwocky
`Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe.
Students in Joseph Keierleber’s Wednesday BIO106K
lab section do not need to turn in their Lab 10 reports
until Wed April 16, rather than Wed April 9.

Narrator #1: Nobel laureate Paul Berg:
“Only rarely is there an opportunity to
participate in a molecular happening.”
Narrator #2: female voice, reading an altered version
Of Lewis Caroll’s Jabberwocky. Very inspiring.
Jabberwocky
`Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe.
Narrator #3: male voice, Just very “inspired”.
transcription unit - the part of a gene that gets copied (transcribed) by RNA polymerase
promoter – the genetic information in the DNA that tells where, when, and how much the gene should
be expressed.
------------------------------coding region – For genes that make (encode) proteins, the coding region is part of the transcription unit.
The coding region is the genetic information in the DNA that tells the specific structure (primary amino
acid sequence) of the protein to be made. The aquaporin protein has a specific structure due to the primary
amino acid sequence and the specific structure of a protein gives each protein a specific function. Again,
the coding region provides the information for the primary acid sequence of the protein to be made.
