Final answer:
The complementary strand of mRNA for the given DNA sequence TAC-GGA-TAA-СТА-COG-GGT-ATT-САА would be AUG-CCU-AUU-GАU-GUC-CCA-UAA-GUU.
Step-by-step explanation:
The complementary strand of mRNA can be determined by replacing each DNA base with its complementary RNA base.
In DNA, adenine (A) pairs with thymine (T), while cytosine (C) pairs with guanine (G). Since RNA does not contain thymine, it is replaced by uracil (U).
Therefore, the complementary strand of mRNA for the given DNA sequence TAC-GGA-TAA-СТА-COG-GGT-ATT-САА would be AUG-CCU-AUU-GАU-GUC-CCA-UAA-GUU.
