Question

Replicate the DNA strand below by writing its complementary strand. A T C T T G C A A A G G C T

Answer 1

Answer: The complementary strand is TAGAACGTTTCCGA.

Explanation: A complementary strand of a DNA is a DNA strand which is not the same with the template strand in base sequence and composition but wherever adenine is found in the template strand, thymine occurs in the complementary strand and wherever guanine occurs in the template strand, cytosine occurs in the complementary strand.

According to Watson and Crick base pairing rule, adenine pairs with thymine (A=T) while cytosine pairs with guanine (C=G).
