Detailed explanation-1: -Answer and Explanation: For the sequence 5’-GATTACA-3’, the complementary DNA strand would be 3’-CTAATGT-5’. Often, DNA strands are written in the 5’ to 3’ direction, so the complementary strand would be 5’-TGTAATC-3’ when written 5’ to 3’.
Detailed explanation-2: -The replication process DNA double helix. Hydrogen bonds break and helix opens. Each strand of DNA acts as a template for synthesis of a new, complementary strand. Replication produces two identical DNA double helices, each with one new and one old strand.
Detailed explanation-3: -What is the complementary strand of bases for a strand with the bases TACGTT? The complementary strand of bases for a strand with the bases TACGTT is ATGCAA.
Detailed explanation-4: -The base sequence in one of the strands of DNA is TAGCATGAT.
