Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If the template strand of DNA is AGATGCATC what is the complementary strand?
A
TCTACGTAG
B
CTACGTAGA
C
AGATGCATC
D
AGACGTCTA
Explanation: 

Detailed explanation-1: -Answer. would be TCTACGTAG being that A and T go together and G and C go together.

Detailed explanation-2: -The if given the base sequence for one strand: 5’-AGGTCCG-3’, the complimentary strand must have the sequence: 3’-TCCAGGC-5’. This ensures that A only pairs with T, and C only pairs with G.

Detailed explanation-3: -The coding, or non-template, strand is the DNA strand complementary to the template strand; it has the same sequence (except for T for U substitutions) as the mRNA.

Detailed explanation-4: -Thus, sequence of bases on complementary strand would be TACGTACGT.
