The type of molecules that contains the alcohol glycerol are PHOSPHO-LIPIDS.
Glycerol is a three carbon alcohol on which some phospholipids are built. Phospholipids which are derived from glycerol are called phosphoglycerides.
The process of fusing two or more DNA molecules to produce a hybrid is known as recombinant DNA. Restrictions endonucleases and ligases are two classes of enzymes that enable the technique.
When a restriction endonuclease detects a particular DNA sequence, it makes cuts inside or near that sequence. The recognition sequence of a restriction enzyme will haphazardly appear on every (1–4)n bases along a random DNA chain. The equation states how many fragments ends (measured in moles) are produced when a restriction enzyme cuts DNA.
Moles of DNA ends =2x(grams of DNA)/(number of bp)(660 g/mol / bp).
The equation describes how many ends are produced when circular DNA is digested by a restriction enzyme.
Mole ends=2x(moles DNA)x number of restriction sites.
The following equation can be used to determine how many ends are produced during the digestion of a linear molecule by a restriction endonuclease.
Mole ends=2x(molesDNA)number of restriction sites +[2x(moles of DNA)].

Reading through the entire investigation before beginning the procedure can help prevent accidents by giving you the knowledge of what to do beforehand and preparing you for what is to come.

Explanation:
1)The cell membrane functions as a semi-permeable barrier, allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell. Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model (also referred to as the fluid-mosaic model). The most common molecule in the model is the phospholipid, which has a polar (hydrophilic) head and two nonpolar (hydrophobic) tails.
2) simple diffusion across the cell plasma membrane. The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down the concentration gradient is , by simple diffusion.
3) some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic or however, because they are charged the polar, they can't cross the phospholipid part of the membrane without help .
4) during fission a copy of the DNA is made and attached to the cell membrane as well. As this cell elongate in preparation for fission, the two DNA copies are pulled apart two opposite ends of the cell. New membrane material is deposited between the two ends of the cell, and a new wall grows between them .

6) example of passive transport and active transport across a cell membrane so, cell membranes are semipermeable meaning they have control over what molecules can or cannot pass through. Some molecules can just drift Inn.
