Their
cool Molecular Biology Machine
has it the other way
though.

A lot of beautiful left handed DNA art
(Until they reverse the gif's that is :-).

This is good news for those of us investigating
the biology of the space invaders.

QIAGEN
advertisement in Science Vol 276, 16 May 1997,
page 1018.
The advertisement claims that
it is now easy to
extract left handed DNA from a variety of plants
that look much like Earth plants. Beware!
Because of their reversed biochemistry, they
are probably poisonous to eat.

Left handed DNA is next to outlines of beings
similar to humans.
-
The journal
Human Mutation
has a web page
that appears to be reporting on
newly discovered mutations
in
CT
(contra-terran, ie anti-matter and therefore reversed handed) humans.
(It has recently been shown that not only are there
biochemically reversed left handed animals, whose
biochemistry is reversed, but also there are those
that are reversed because they are made of antimatter. ;-)
(Note: The print journal cover is right handed.)
- Technology Review
July 1997 page 47.
A left handed DNA winds around a medical staff.

by David Eliot Brody and Arnold R. Brody,
Paperback, 400 pages.

The cover of the book shows a left handed DNA, so the text
may be especially meaningful for
CT
humans.
-
Science
advertisement in Science Vol 276, 27 June 1997,
page 2084.
Three flags made from left handed DNA, with a heading that
"THE RACE IS ON ..."

1401-1406, 1997.
Figure 1 on page 1402
shows the strand breakage and reunion in site-specific
recombination in the Lambda Int family.
At the moment of rejoining the DNA strands all
switch from right handed to left
handed symmetry.
The topological consequences of this switch have not been
carefully considered.

Advertisement flyer for molecular biology books, 1997 December 31,
shows a spectacular right handed DNA switching midstream
into a left handed one, and a large left handed one in between
the "bible for molecular biologists" and "[almost]
an entire library of contemporary molecular biology [squeezed] into
one volume".

It's pretty easy to see, but making it bigger makes clear that
the left handed twist runs through the entire image:

You don't believe me? I couldn't believe there was
a second one either. Here it is enlarged:

The Journal of Biological Chemistry
(272: 7567-7569, page 7568,

requires binding to left handed DNA.

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?
