Please match the type of mutation with the BEST description.
1. Nonsense A. Codes for a stop codon
2. Spontaneous B. A form of induced mutation
3. Addition/frameshift C. Occurs during normal cell division
4. Transposons D. A mutation that may have no effect
5. Substitution/point E. Results in an altered protein

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

because the light is a great source of energy for the plants to survive. (i hope this )
