A single DNA molecule switches from left- to right- handed.
Where the right hand DNA is inspected under a magnifying
glass, it becomes left handed. Something is strange about those
optics!

A single DNA molecule is left-handed and switches to a right
hand twist as one goes up the page.
This mistake is gaining in popularity!

DNA reverse handedness?

- Clontech 96/97 catalog.
The cover shows a series of left handed DNAs coming out
of a machine; the DNAs are stamped "innovation".
How are they going to use this innovative product?
In the Chapters on PCR-Based Analysis, they show
another picture where a left handed DNA is replicated
into both left and right handed DNA! Does this mean
that they have invented a left handed enzyme?
For the section on Libraries, they show a box from
which a right then left twist DNA appears from a box.

Apparently they have a way to amplify left handed DNA!

of the journal Gene!
By Spring of 1997,
they had corrected the error.
- Scientific American, September 1996:
pages 56-57: people against a background of left handed DNA.

page 64: both left and right handed DNA in a normal cell
page 109: DNA hybridizing to "normal" DNA from Hubert Humphrey has a left
handed twist. What was he ...?
The editors responded:
"Thanks for pointing out our error in the September issue regarding the
handedness of DNA. We have alerted the artists and editors involved. We
appreciate your interest in SCIENTIFIC AMERICAN.
Sincerely,
THE EDITORS"

The cover of the book Independent Birth of Organisms
by
Periannan Senapathy
Shows that frogs came from right handed DNA but that
crabs came from left handed DNA.
No wonder he claims "that evolutionary theories are fundamentally incorrect".

For your first visit to the
Left Handed
Hall of Fame
page I suggest that you follow the story
over all of the years.
After that you can look at each year individually
from the table below.
Note: just because a year has gone by does not mean
we haven't found more examples for that year!
1997 and 1998 were bumper crop years
and 1999 beat them more than 2 fold.
2000 was a record year, thanks to help from
friends around the world
(60 of the 97 cases, 63%!).
2001 exceeded even that record!
2002 was lower - are we making headway?
