Final answer:
In Biology, the complementary DNA sequence to a given strand like 5'-AATGCTAC-3' is formed following the base pair rules, resulting in a complementary strand 3'-TTACGATG-5'.
Step-by-step explanation:
The question posed is relevant to the subject of Biology, specifically regarding the structure of DNA and RNA sequences. When DNA and RNA are synthesized, the nucleotides adenine (A), thymine (T), cytosine (C), and guanine (G) in DNA, or uracil (U) in RNA, pair up in a way that is complementary. For DNA, A pairs with T and G pairs with C, while in RNA, A pairs with U and G still pairs with C.
The question provides various strings of these bases and asks for the complementary sequence to be identified for a given DNA sequence strand. The provided sequences demonstrate base pairings and the construction of complementary strands in transcription and replication in Biology. To answer the DNA-related questions, just look at the base pair rules mentioned and form the opposite strand accordingly. For instance, if the sequence is 5'-AATGCTAC-3', then the complementary DNA sequence would be 3'-TTACGATG-5' following the A-T and G-C pairing.
