Read the following statements regarding transcription: (a) DNA-dependent RNA polymerase catalyses polymerisation in only one direction, that is, 5' 3'. (b) The DNA strand with polarity 3' 5' acts as the template. (c) The coding strand has the polarity 5' 3' and its sequence is identical to the transcribed RNA except for having thymine in place of uracil. (d) The terminator is located towards the 3' end of the coding

Step-by-step solution

Statement (a) is correct. DNA-dependent RNA polymerase catalyses polymerisation in the 5' 3' direction only. Statement (b) is correct. Since polymerisation occurs in the 5' 3' direction, the template strand must have 3' 5' polarity. Statement (c) is correct. The coding strand has 5' 3' polarity. Its sequence is the same as the newly synthesised RNA, except that DNA contains thymine (T) whereas RNA contains uracil (U). Statement (d) is correct. The terminator region is located downstream, which is defined as towards
