14: Operons allow prokaryotes to replicate DNA at the appropriate time.
Operons are specific regions of genes that are linked to a singular process. They ensure that the expression of these genes does not go unchecked and only occurs when necessary. Two key examples of this in humans are the lac operon and trp operon.
15. The central dogma of molecular biology is:
DNA to RNA to Proteins
Protein Synthesis occurs in 3 steps.
First our DNA is translated into RNA. Next the RNA is sequenced into Amino Acids by reading the corresponding 3-Base Codons. These Amino Acid sequences form various protein structures.

Answer:
The correct answer is - to protect the cells of these secretory glands from pepsin.
Explanation:
Pepsinogen is an inactive form of enzyme pepsin that is released by specific cells called chief cells within the gastric lining Releasing the inactive form of pepsin in preventing the auto-digestion of protective proteins and the cells of these secretory glands in the lining of the digestive tract.
Pepsinogen is activated by acidic pH to pepsin of the stomach lumen and the cell lining of the stomach is protected by mucus lining.
Answer:
b
Explanation:
Internal respiration is the process of diffusing oxygen from the blood, into the interstitial fluid and into the cells.
