Is the process of mitosis complex?
Mitosis is a highly complex process consisting of six distinct sequential stages – prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis (Figure 2).
What is the most complex stage of mitosis?
prophase
Meiotic prophase. Meiosis involves two rounds of chromosome segregation and thus undergoes prophase twice, resulting in prophase I and prophase II. Prophase I is the most complex phase in all of meiosis because homologous chromosomes must pair and exchange genetic information.
How does mitosis contain complex organisms?
In multicellular organisms individual cells grow and then divide via a process called mitosis, thereby allowing the organism to grow. Cellular division and differentiation produce and maintain a complex organism, composed of systems of tissues and organs that work together to meet the needs of the whole organism.
What does the Synaptonemal complex do?
The synaptonemal complex (SC) is a meiosis-specific structure formed between homologous chromosomes during prophase that promotes DSB formation and biases repair of DSBs to homologs over sister chromatids.
What are 3 purposes of mitosis?
Mitosis is important for three main reasons: development and growth cell replacement and asexual reproduction.
- 1. Development and growth. After meiosis has produced a gamete, and this has fused with another gamete to form an embryo, the embryo grows using mitosis.
- Cell replacement.
- Asexual reproduction.
What happens to the cell during mitosis?
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.
