lol i hate this question........its in meh science book
The complimentary strand of MRNA would be AAUUCCGG.
The order of bases in the second strand of a DNA molecule is complementary to the first strand, following the base pairing rules (A with T, C with G). So, if the first strand has the sequence ATCG, the second strand would have the sequence TAGC.
The complementary base pairing rule for DNA and mRNA is: A pairs with U, T pairs with A, G pairs with C, and C pairs with G. Therefore, the mRNA complementary strand for the DNA sequence TTAAGGCC would be AAUUCCGG.
TGCA
Since A pairs with T, and G pairs with C, then the sequence of bases in the strand of DNA being copied determines the sequence of bases in the newly copied strand. The bases are complementary (A gives T and G gives C when copied).
The complementary sequence of a DNA strand is written with the beginning letters of the bases: adenine (A), cytosine (C), guanine (G), and thymine (T). You would replace each letter with its complementary nucleotide. Replace: A for T T for A C for G G for C
TGCA
A matching strand of DNA to the sequence AGTAAC would be its complementary strand, which consists of the bases that pair with each nucleotide. In DNA, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). Therefore, the complementary strand to AGTAAC would be TCATTG.

complementary to each other, meaning that the sequence of bases in one strand determines the sequence in the other strand. This allows for accurate replication of genetic information during cell division and ensures genetic stability in offspring.
During DNA replication, the enzyme DNA polymerase catalyses the formation of new strands of DNA, using the old strands as models. DNA has a double-helix structure, with two strands forming each helix. Each strand is made up of DNA nucleotides, with the genetic information encoded in the sequence of different nucleotides (different nucleotides are distinguished by molecules called 'bases' attached to them, so the sequence of nucleotides is known as the 'base sequence'). The base sequence of one strand is complementary to that of its' neighbour - the base A binds with T, and C with G, so if one strand had the sequence ATTACA, the base sequence of the complementary strand would be TAATGT. When DNA polymerase creates a new DNA strand, it does so by matching nucleotides to the base sequence of one of the strands - the template strand. New nucleotides are brought in, which match the template in a complementary fashion (ie. A-T, C-G), and join to become one new strand. This new strand is complementary to the template.
The enzyme responsible for adding complementary DNA bases to an exposed DNA strand is DNA polymerase.
