Meiosis, or reductional division, is a process during which exchange of genetic material between the homolog chromosomes (crossing-over and recombination) takes place and such a division of the genetical material occurs the four daughtercells
have received each only one set of chromosomes (they are haploid, in
contrast to the mother cell which contained homolog chromosomes and was
diploid)
<span>have each a distinct genetical composition, also different from that of the parental cell.
Meiosis is divided into twofases: meiosis I and meiosis II.
</span>
Meiosis<span> has two rounds of genetic separation and cellular division while </span>mitosis<span>only has </span>one<span> of each. In </span>meiosis<span> homologous chromosomes separate leading to daughter cells that are not genetically identical. In </span>mitosis<span> the daughter cells are identical to the parent as well as to each other.</span>
<span>The answer to the question stated above is letter A. Cell Structure.
In the new 6-kingdom system of classification, like the old 5-kingdom system, organisms are basically grouped by</span><span> cell structure.
The new 6-kingdom system of classification includes the following:
</span>Animalia<span>, </span>Plantae<span>, </span>Fungi<span>, </span>Protista<span>, </span>Archaea/Archaeabacteria<span>, and </span>Bacteria/Eubacteria.
S-phase
S-phase is the part of the cell cycle in which DNA is replicated, occurring between G1 phase<span> and G</span>2 phase<span>. Precise and accurate DNA replication is necessary to prevent genetic abnormalities which often lead to cell death or disease.</span>
