1.	Define with example :(i) Isoelectric point (ii) Mutarotation (iii) Transcription
Answer» (i) Isoelectric point : The pH at which there is no net migration of any ion towards electrode e.g., amino acids have isoelectric point at pH = 5.5-6.3. (ii) Mutarotation : It is spontaneous change in optical rotation when an optically active substance is dissolved in water e.g., a glucose when dissolved in water changes its optical rotation from 111º to 52.5º. (iii) Transcription : It is process by which m-RNA is generated from DNA e.g., if DNA has base sequence ATACA then m-RNA has base sequence UAUCGU
