WebStephen M. Wolniak. Mitosis is the process that facilitates the equal partitioning of replicated chromosomes into two identical groups. Before partitioning can occur, the chromosomes must become aligned so that the separation process can occur in an orderly fashion. The alignment of replicated chromosomes and their separation into two groups is ... WebStart studying Mitosis. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Home.

During prophase I homologous chromosomes make contacts with each other called chiasmata and “crossing over” occurs. This is where chromosomes exchange sections of DNA. clm meaning slang

Meiosis is a rather long process than that of mitosis because it takes place in two cycles involving the separation of chromosomes. The process is longer due to the phases of prophase which takes place in two phases i.e prophase I and prophase II. WebPhases of mitosis Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).
