A and T pair together, and G and C pair together. There are no U’s because U’s are in RNA, not DNA.
The two kinds of basic cell division include mitosis and meiosis.
Mitosis is where a parent cell divides and produces 2 genetically indentical daughters cells. So this means that when the cell division is complete, the number and even the sequence of chromosomes is exactly same as the original parent cell.
And in meiosis, also called reduction division, is where the parent cell divides and produces 4 genetically different daughter cells, which has only half of the number of chromosomes than that of the original parent cell. This process has to go through 2 times of divisions.
Mitosis is usually seen in most somatic cells, it is very important to activities such as growth, repair etc. Meanwhile, meiosis is seen in gametes, and its important for sexual reproduction.
