Question

1. if rna polymerase is reading the dna strand below, what is the mrna strand that would be created? dna strand: taccg aatgtat rna strand: __________________________

Explanation:

Step1: Recall base - pairing rules

In transcription, RNA polymerase pairs adenine (A) with uracil (U) (since RNA has U instead of T like DNA), thymine (T) with adenine (A), cytosine (C) with guanine (G), and guanine (G) with cytosine (C).

Step2: Apply base - pairing to the given DNA strand

For the DNA strand \(TACCGGAATGTAT\):

• \(T\) pairs with \(A\)
• \(A\) pairs with \(U\)
• \(C\) pairs with \(G\)
• \(G\) pairs with \(C\)
• \(G\) pairs with \(C\)
• \(A\) pairs with \(U\)
• \(T\) pairs with \(A\)
• \(G\) pairs with \(C\)
• \(T\) pairs with \(A\)
• \(A\) pairs with \(U\)

Answer:

\(AUGGCCUUACAUA\)
