Question:

Write brief note on the following
a. Synaptonemal complex
b. Metaphase plate

Answer:

During zygotene stage of Prophase I chromosomes start pairing together which is called synapsis and these paired chromosomes are called homologous chromosomes. Synaptonemal complex is made up of protein formed between two homologous chromosomes. It contains a recombination nodule which consists of enzyme recombination involved in crossing over.
Metaphase line is considered as an imaginary line which is formed in the center of the cell during Metaphase, which is equidistant from the two opposite poles. This allows the chromosomes a place to be lined up on before they are pulled apart.
