Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:

How can we tell the difference of the two?Which of the following (could be more than one) would not be a rational explanation for why the three-dimensional structure of a protein is driven and stabilized largely by noncovalent rather than covalent bonds?a) Proteins may be degraded for energy, and if their three-dimensional structures were heldtogether by mostly covalent bonding, this might be too difficult to accomplishb) Proteins will need to be unfolded to cross biological membrane, and if their three-dimensionalstructures were held together by mostly covalent bonding, this might be too difficult toaccomplish.c) Protein function (transport, enzyme catalysis, etc...) may require flexibility in the three-dimensional structure to allow for conformational change, and if protein three-dimensionalstructure were held together by mostly covalent bonding, this might be too difficult toaccomplish.d) All of the answer choices are rational explanations for why the three-dimensional structure of protein is driven and stabilized largely…Mild, non-ionic detergents (like Triton X-100, with polar but uncharged regions that do not denatureproteins) would be required for separation of which of the following proteins from cell membranes?A. monolayer-associated proteinsB. lipid-linked proteinsC. transmembrane proteinsD. integral proteinsE. peripheral proteins
