Question

Check all ways below to ensure that the bases in RNA are properly paired.

The template DNA would be 3’ GUCUACAUGCCUGCUAUU 5’.

The mRNA strand is complementary to the DNA template strand.

During transcription, G in DNA pairs with C in mRNA, and A in DNA pairs with U in mRNA.

Answer 1

A few corrections and confirmations:

1) DNA uses T (thymine), not U. Your "template DNA" written with U should use T. The correct template DNA (3' → 5') is:
3' GTCTACATGCCTGCTATT 5'

2) mRNA is complementary and antiparallel to the DNA template (template 3'→5', mRNA 5'→3'). The mRNA sequence (5' → 3') complementary to that template is:
5' CAG AUG UAC GGA CGA UAA 3'
(or written without spaces: 5' CAGAUGUACGGACGAUAA 3')

3) Base-pairing rules during transcription (DNA → RNA):
- DNA G pairs with RNA C
- DNA C pairs with RNA G
- DNA A pairs with RNA U
- DNA T pairs with RNA A

So: your statement that the mRNA is complementary to the DNA template is correct. Your statement that DNA G pairs with RNA C and DNA A pairs with RNA U is also correct, but you should also include the C→G and T→A pairs.
