If the following DNA strand was used as a template, what would the sequence of an RNA be? 5\' GTACCGTC 3\' a. 5\' GUACCGUC 3\' b. 5\' GACGGTAC 3\' c. 5\' CAUGGCAG 3\' d. 5\' GACGGUAC 3\' e. 5\' GUCGGUAC 3\'

Solution

Ans 9 A 5\' GUACCGUC 3\'

The polarity of RNA transcript is always 5\' -3 \' as RNA polymerase can catalyse the transcription in only one direction.

Hence the strand given in tne question is the coding strand of DNA template, so the bases in RNA will be exactly same as given in the strand. Only thymine will ne replaced by uracil.
