General Science and biology as a part of it, is an integral part of the UPSC syllabus. Many questions are asked from this section every year in the IAS question paper. Apart from general science questions, questions are asked from the science and technology section also. This is also related to the current affairs section. Even though you must be abreast of the latest developments from the field of science, it is important that you go through the basic sciences as well. For this, the NCERT textbooks are the best bet because they talk about basic science in a very simple and clear language.
