The synaptonemal complex will formed in which stage
of meiosis I ?
The synaptonemal complex will formed in which stage of meiosis I ?
The correct option is C Zygotene
During leptotene
stage the chromosomes become gradually visible under the light
microscope. The compaction of chromosomes continues throughout leptotene. This
is followed by the second stage of prophase I called zygotene. During this stage chromosomes start pairing together and
this process of association is called synapsis. Such paired chromosomes are
called homologous chromosomes. Electron micrographs of this stage indicate that
chromosome synapsis is accompanied by the formation of complex structure called
synaptonemal complex. The
complex formed by a pair of synapsed homologous chromosomes is called a bivalent or a tetrad. However, these
are more clearly visible at the next stage.
