Final answer:

The complementary DNA sequence of the given strand AGTCCGA UCAGGCU AGUCCGA TCGGACT TCAGGCT, considering antiparallel orientation and base pairing rules, is TCCTGAG TCCGGAT TGACCGA AGTCCGA AGTCCGA in the 3' to 5' direction.

Step-by-step explanation:

The question asks for the complementary DNA sequence of a given strand, which is a fundamental concept in biology, particularly in genetics and molecular biology. In DNA, the two strands are antiparallel, meaning they run in opposite directions, and the nucleotides pair up in a specific way: adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). Given the DNA sequence AGTCCGA UCAGGCU AGUCCGA TCGGACT TCAGGCT, we need to provide its complementary strand, which would adhere to this pairing and be oriented in the 3' to 5' direction.

The complementary DNA sequence, aligned with the base pairs and written in the 3' to 5' direction is TCCTGAG TCCGGAT TGACCGA AGTCCGA AGTCCGA. This ensures that each base is paired correctly with its complement on the opposite strand.
