Answer:
In normal cells, the cell cycle is controlled by a complex series of signaling pathways by which a cell grows, replicates its DNA and divides. ... In cancer, as a result of genetic mutations, this regulatory process malfunctions, resulting in uncontrolled cell proliferation.
Answer:
The correct option is b
Explanation:
Phospholipids are lipids that contains a phosphate group, which forms the "head" of the molecule and is hydrophilic (water loving). The "tail" of phospholipids is made of two fatty acids which are hydrophobic (water fearing). The phospholipid in the cell membrane acts as a selectively permeable barrier that regulates what goes in and out of the cell <u>thereby protecting the cell from some external molecules and ions</u>.
Answer: Peptide bond
Explanation: A peptide bond is the covalent chemical bond bond that holds together two amino acids which occurs when the carboxylic group of one molecule reacts with the amino group of the other molecule, linking the two molecules and releasing a water molecule catalyzed by peptidyl transferase, an RNA-based enzyme integrated into the growing chain.
In the elongation stage ie when Long chain polypeptides are forming , peptide bonds are formed by linking many amino acids to each other. These peptide bonds of amino acids are relatively unstable, and can break spontaneously in a slow process as can be seen especially in enzymes of living organisms in the making and breaking of bonds.
