Description : If the stomach did not produce any hydrochloric acid, which enzyme will not function? (1) Ptyalin (2) Rennin (3) Pepsin (4) Lipase
Last Answer : (3) Pepsin Explanation: Hydrochloric acid converts pepsinogen into an enzyme called pepsin. When food enters the stomach, hydrochloric acid production increases and the pH may fall to as low as 1 or 2, a very acidic condition.

Description : An important step in protein synthesis is transcription. Which of the following statement(s) is/are true concerning this process? a. The first step in gene transcription involves separating the double helix ... nucleus to the cytoplasm d. Only one protein can be produced from an initial mRNA strand
Last Answer : Answer: c Transcription of a gene begins at an initiation site associated with a specific DNA sequence, termed a promoter region. After binding to DNA, the RNA polymerase opens up a short ... different proteins from the same gene. mRNA is exported from the nucleus only after processing is complete
