Maternal autosomal chromatids
Tetrads
Is this a 1N or 2N cell?
What process is this?
Solution
The entire process is of mitosis which involves cell division to create two new cells and has following stages.
G2 phase: DNA duplicates and are called sister chromatids. Has two controsme.
Prophase: chromosome start to condense and mitotic spindle begins to form. Nucleolus disappears.
Prometaphase: Breaking of nuclear envelope, capturing of chromosome by microtubules called kinetochores.
Metaphase: chromosome line up at metaphase plate and are ready to divide.
Anaphase: sister chromatids seperate and pulled to opposite pole.
Telophase: Breaking of mitotic spindle, formation of two nuclei and each set of chromosome
Cytokinesis: Division of cytoplasm and formation of two new cells.
Since two cells are formed it is called 2N
