These nucleic acids differ in three key ways: DNA is double-stranded, while RNA is single-stranded; DNA contains the sugar deoxyribose, whereas RNA contains ribose; and while each DNA nucleotide has as its nitrogenous base either adenine (A), cytosine (C), guanine (G) or thymine (T), in...
The phase in which mitosis typically goes wrong is called the metaphase, when the chromosomes align at the metaphase plate. If the duplicate chromosomes do not pair properly at the metaphase plate, they will not move properly to each pole during anaphase. This results in one cell having two c...

What happens in each mitosis phase? There are four stages of mitosis: prophase, metaphase, anaphase and telophase.1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase...
This process ensures that each daughter cell will contain one exact copy of the parent cell DNA. What Are the Phases of Mitosis? Mitosis consists of five morphologically distinct phases: prophase, prometaphase, metaphase, anaphase, and telophase. Each phase involves characteristic steps in the ...
