These were in the ground a while and plants grew before I planted 2 rows of red skin potatoes beside them. I just recently dug up all 5 rows. I have no white potatoes, all 3 rows of white potatoes, and they were white when i planted them, but all 3 rows came out of the ground red.
chromosome replication takes place during interphase of cell division process. due to cell division one cell divides into two ( in case of mitosis) or 4 daughter cells ( meiosis).
Only occurring in a cell once per (cell) generation, DNA replication in humans occurs at a rate of 50 nucleotides per second, 500/second in prokaryotes. Nucleotides have to be assembled and available in the nucleus, along with energy to make bonds between nucleotides.
