Question

Synapsis is the process of pairing together of two ________.

• A. sister chromatids
• B. non-homologous chromosomes
• C. sister chromatids of non-homologous chromosomes
• D. homologous chromosomes

Answer 1

The correct option is D homologous chromosomes

Synapsis is the pairing of homologous chromosomes that start during the zygotene phase of prophase I of meiosis I. It is essential for the recombination of genetic material between homologous chromosomes.
Each of the homologous chromosomes are composed of two identical sister chromatids which are formed as a result of DNA replication during S-phase of the cell cycle.
