Abstract
In their comment E. M. Terentjev and M. Warner try to argue that the r esults we obtained in ref. [1] are physically incorrect. To do this th ey use estimates of the orders of magnitude, and their scaling with cr oss-linking density, of a number of elastic coefficients. We point out that their arguments are based on their misunderstanding of several b asic concepts. First, they confuse the Landau model to describe phase transitions with a macroscopic description of the nematic phase. Secon d, they apply the technique of a linear stability analysis above the t hreshold of the instability, where this type of analysis is incorrect.
