Biology
During S phase of interphase, semi-conservative replication of DNA occurs. Complementary base pairing rules are adhered to (on complementary strands, A is paired with T; C is paired with G). During anaphase, sister chromatids are separated and move to opposite poles of the cell. New cells have the same number and kind of chromosomes as their parents.
- Mitosis
Prophase Chromatin condenses to form chromosomes. Centrioles migrate to opposite poles of the cells (except in plant cells which do not have centrioles). Microtubules develop and form a star shaped structure known as an aster, and spindle fibres may develop....

Similarities: Both processes occur in the nucleus. Both processes also involve specific complementary base pairing. Both processes involving the unwinding of the double helix DNA. Both processes involve forming of hydrogen bonds between the original DNA...

DNA molecule consists of nucleotides in which the sugar component is deoxyribose whereas the RNA molecule has nucleotides in which the sugar is a ribose. Nucleotides Roles: are monomers for nucleic acid polymers, such as DNA and RNA....

Mitosis is a nuclear division giving rise to genetically identical cells in which the chromosome number is maintained by the exact duplication of chromosome. Significance of mitosis production of geneticlly identical cells: It keeps the chromosome...
