Detailed explanation-1: -The sequence for AACGTAACG in mRNA molecule synthesized after transcription from a DNA strand shall be UUGCAUUGC.
Detailed explanation-2: -A strand of DNA with the sequence AACTTG will have a complimentary strand with the sequence. Explanation: There are four nitrogenous bases. They help in relation of one of the strand of the DNA with the others strand.
Detailed explanation-3: -Answer and Explanation: The complementary DNA strand of the sequence ATGC will be TACG. The complementary base pairing in DNA is as per the Chargaff’s rules. According to these rules, purines always hydrogen bond with pyrimidines and vice-versa.
Detailed explanation-4: -DNA replicates by a semi-conservative method in which each of the two parental DNA strands act as a template for new DNA to be synthesized. After replication, each DNA has one parental or “old” strand, and one daughter or “new” strand.
