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).
The problem of how DNA replication occurs only once in each cell cycle has been partially resolved by studies in the fission yeast, Schizosaccharomyces pombe, where genetic approaches have been used to study the sequential coupling of the S and M phases. As will be discussed, Cdk are implicated as central regulators.
