Your body size will become bigger and bigger.
Which is the longest phase of cell cycle-
Interphase
Monophase
Meiosis
Mitosis
Chromosomes are made up of-

In metaphase-
Nucleus disappear and chromosomes line up at the middle of the cell.
Chromosomes start moving randomly.
Chromosomes decondense.
Chromosomes clump at the middle.
Chromosomes move to opposite sides of the cell with the help of formed by centrioles.
Spindle fibres.
Amino acids.
Proteins.
Centrosomes.
Cytokinesis occurs after mitosis which divides the to form two identical cells.
Cytoplasm
Nuclei
Chromosomes
Proteins
Why does our body undergo mitosis?
fun and games
