What will be the sequence of mRNA produced by the following stretch of DNA?
3’ ATGCATGCATGCATG 5’ Template strand
5’ TACGTACGTACGTAC 3’ Coding strand
3’ ATGCATGCATGCATG 5’ Template strand
5’ TACGTACGTACGTAC 3’ Coding strand
View answer and explanation
Correct option: B
5’ UACGUACGUACGUAC 3’
Option B (5’ UACGUACGUACGUAC 3’) is correct because the mRNA sequence will be the same as the coding strand, except that Thymine (T) is replaced by Uracil (U).
