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.
Ww and O 75 is the answer
Answer:
These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed to the next generation.
Answer:
The correct answer would be - medium with lactose present and glucose absent.
Explanation:
There are genes present in lac operon that takes part in the lactose metabolism. These genes expressed only if a medium has lactose in absence of glucose.
In the absence of glucose and lactose is present, due to inducer the lac repressor is removed from the operator. This leads to the binding of CAMP to DNA as the CAMP levels are high. It helps in high transcription levels b binding RNA polymerase to promotor.
