Consider the replicated strand of DNA: 3'-ATCGGGAAATTCGGA-5 .' Which of the following choices shows the template strand of DNA used for replication?
A) 3'---ATCGGGAAATTCGGA-5'
B) 5'---ATCGGGAAATTCGGA---3'
C) 3'---TAGCCCTTTAAGCCT---5'.
D) 3'---TAGCCCTTTAAGCCT---5'..
E) 5'---UAGCCCUUUAAGCCU---3'

The template strand used for DNA replication is complementary to the replicated strand, so it must have the opposite nucleotide sequence. Choice C has the opposite nucleotide sequence, with every nucleotide being complementary to the corresponding nucleotide on the replicated strand. Choices A, B, and D have the same nucleotide sequence as the replicated strand, so they cannot be the template strand. Choice E includes a U nucleotide, which is not present in DNA, indicating that it is not a valid option. Therefore, the correct choice is C.
