Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which RNA bases would pair with the DNA sequence TACGAA in transcription?
A
AUGCUU
B
ATGCTT
C
GCATCC
D
GCAUCC
Explanation: 

Detailed explanation-1: -In the complementary strand of DNA, the bases that bind to TAC are complimentary, thus they are ATG.

Detailed explanation-2: -DNA and RNA bases are also held together by chemical bonds and have specific base pairing rules. In DNA/RNA base pairing, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G). The conversion of DNA to mRNA occurs when an RNA polymerase makes a complementary mRNA copy of a DNA “template” sequence.
