During transcription, the sequence of the template strand of a transcription unit is given as: 5' - C G A T A G C C G T A T G C A - 3' Which of the following represents the correct sequence of the newly synthesized RNA transcript?
Options
- A5' - C G A U A G C C G U A U G C A - 3'
- B5' - T G C A T A C G G C T A T C G - 3'
- C5' - G C U A U C G G C A U A C G U - 3'
- D5' - U G C A U A C G G C U A U C G - 3'
Correct answer
D. 5' - U G C A U A C G G C U A U C G - 3'
Step-by-step solution
The sequence of the template strand is given as: 5' - C G A T A G C C G T A T G C A - 3' During transcription, RNA polymerase reads the template strand in the 3' 5' direction and synthesizes the RNA transcript in the 5' 3' direction. Writing the given template strand in the 3' 5' direction, we get: 3' - A C G T A T G C C G A T A G C - 5' The newly synthesized RNA transcript will be complementary and antiparallel to the template strand. In RNA, Adenine (A) pairs with Uracil (U) instead of Thymine (T), and Cytosine (
