Cell Size, Presence of other cells, and Chemical Stimulators
The enzyme responsible for facilitating hydrogen bonding between nucleotides in a new DNA molecule is Polymerase.
Lipid Bilayer.A plasma membrane is made up of Lipid Bilayers, which consists of polar phosphate heads, which are hydrophilic or water loving, and non-polar fatty acid tails, which are hydrophobic. Proteins are embedded in the membrane as well.Cell membranes are known to have holes, or selective permeable.
