such genes contained a sequence
of amino acids divisible by a cer-
tain number — about 125 for an-
imal proteins and 150 for
proteins of bacteria. This should
correspond to about 400 base
pairs of DNA, which according to
studies of other scientists is the
optimal size at which DNA tends
to form a ring.
The finding that many protein
genes are made of standard-size
pieces led the researchers to pro-
pose that such segments must
have once existed separately,
then fused into larger, ring-
shaped structures consisting of
two or three segments, and lat-
er the resulting composite genes
joined to form chromosomes — a
process Professor Trifonov refers
to as combinatorial fusion.
This theory — to be published
soon in the Journal of Molecular
Evolution — was developed by
Professor Trifonov while he was
working at the Institute of Mol-
ecular Medical Sciences in Palo
Alto, Calif., in discussions with
the director of that institute, Pro-
fessor Emile Zuckerkandl, one of
the founders of the discipline of
molecular evolution.
Further supporting this theo-
ry, the researchers have found
signs of "seams," or ancient bor-
ders, between the segments of
125 or 150 amino acids: the

presence of excessive amounts of
the amino acid methionine,
which signals the start of protein
synthesis. While these "border
signs" today have no function
and can merely be regarded as
genetic "fossils," in ancient DNA
rings they may have served as
signals indicating where syn-
thesis of individual proteins must
begin.
Professor Trifonov also says
his findings may help explain the
emergence of introns — DNA
segments that puzzle researchers
because they appear to contain
no useful genetic information. Ac-
cording to him, introns may sim-
ply be remnants of genetic
material that did not encode for
proteins but was responsible for
synthesis of certain other RNA
or DNA molecules that were
functionally important at the
time. (This hypothesis, however,
provides no clues as to which
role, if any, introns play today in
DNA.)
In addition, Professor Tri-
fonov's research may explain the
existence in cells of a small num-
ber of free-floating DNA ele-
ments that are not part of the
cells' chromosomes: These may
be remnants of ancient ring-
shaped genetic segments and of
their early combinations. ❑
Women's Hotline
For The Orthodox
NAOMI GROSSMAN SPECIAL TO THE JEWISH NEWS
n October 1992, a group of Is-
raeli women in Har Nof, a
Jerusalem suburb with a
growing Orthodox presence,
joined forces with American-born
Israeli social worker Debby
Gross. They started a 24-hour
hotline for Orthodox women too
ashamed or uncomfortable to
talk to secular volunteers or pro-
fessionals at existing crisis cen-
ters.
"This could not have happened
10 years ago," Ms. Gross says.
"No one would have admitted
that battered women or abused
children exist in the Orthodox
community. But the community
is more open now, and there is
a high number of incidents. It
can't be ignored anymore."
A five-month training program
was set up in Jerusalem's
Shaarei Zedek Hospital, and af-
ter an initial screening process,
50 Orthodox women volunteers
were invited to participate.
Taught how to deal with
child abuse, sexual abuse
and wife beating, par-
ticipants learned to
recognize when to in-
tervene and how to
help.

Primarily catering to an Or-
thodox audience, the halachic im-
plications of these issues were
also discussed. A woman calling
about serious marital problems,
for example, will be encouraged
to stay with her husband. She
will further be advised not to go
to a non-Orthodox women's shel-
ter since, in a child-custody case,
the courts may rule that the
mother was irresponsible in ex-
posing her children to a secular
environment.
Women who call in saying
they have been raped are en-
couraged to file a report at the po-
lice station, offered psychological
counseling, and told to talk to
their rabbi. Although the topic is
controversial, they are told that
the rabbi may authorize use of a
"morning after" pill. Women with
large families who
