The structure of an RNA strand is much like that of a DNA strand.  However, RNA molecules are usually (                              )-stranded and (                                                                ).

A BCS Class III API pharmaceutical product  is formulated as a test tablet containing a different binder from the reference product. The comparative dissolution testing shows rapid, not very rapid, dissolution (i.e. 85 % in 30 min) in all three media (pH 1,2, 4,5, 6,8) of both test and reference products.  What is the biowaiver status of this product?

Phosphorylation of the carboxyl terminal domain (CTD) of RNA polymerase II by TFIIH would

During pharmaceutical transport, temperature fluctuations frequently occur, which can impact product stability. Which statement best describes the use of Mean Kinetic Temperature (MKT)?

A batch of immediate-release tablets has a dissolution specification of Q = 80 % in 30 minutes:                                                                                                                                      (15)The % dissolved at 30 minutes is measured as follows:   Tablet % Dissolved    S1 (6 tablets) 82, 79, 84, 81, 78, 80   S2 (6 tablets) 83, 85, 79, 80, 81, 82   S3 (12 tablets) 80, 79, 81, 82, 78, 83, 80, 81, 82, 80, 79, 81  Tasks:Calculate the mean % dissolved at tier (S2, S3 as required).Determine whether and at what stage the batch meets the dissolution specification.Explain the regulatory implications of your findings at each tier.
