To determine the complementary DNA strand produced from a given DNA sequence, you need to match each nucleotide with its complementary base: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). For example, if the original DNA strand is 5'-ATCG-3', the complementary strand would be 3'-TAGC-5'. The directionality of the strands is also important, so ensure to maintain the 5' to 3' orientation when writing the complementary sequence.
The template strand of DNA is used to make a complementary copy during DNA replication, while the antisense (non-coding) strand is used as a template for complementary mRNA synthesis during transcription.
To determine the complementary DNA strand, you would pair each nucleotide with its corresponding base: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). For example, if the original strand of DNA is 5'-ATCGTA-3', the complementary strand would be 3'-TAGCAT-5'. This complementary pairing ensures that the two strands are held together by hydrogen bonds, maintaining the double helix structure of DNA.
The template strand is used to make a complementary copy. This is a type of DNA strand.
During transcription, the DNA template is used to create a complementary strand of mRNA (messenger RNA). An A on the DNA template is complementary to a U on the mRNA, T to A and C to G. Therefore the complementary mRNA of TAC-GCG-CAT-TGT-CGT-CTA-GGT-TTC-GAT-ATA-TTA-GCT-ACG is: UTG-CGC-GUA-ACA-GCA-GAU-CCA-AAG-CUA-UAU-AAU-CGA-UGC
AGTCG (I'm assuming your strand was written in the normal 5' to 3' order, and I wrote mine in that order as well, which means the last residue in my strand pairs with the first residue in your strand, and vice versa).
If cga ct were used as a template strand for complementary DNA synthesis, the complementary DNA produced would be gct ga. This is because each nucleotide pairs with its complementary base: cytosine (c) pairs with guanine (g), guanine (g) pairs with cytosine (c), adenine (a) pairs with thymine (t), and thymine (t) pairs with adenine (a). Therefore, the complementary sequence would read from 5' to 3' as gct ga.
The complementary strand of DNA is a strand that matches the sequence of the original DNA strand through base pairing rules. Adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G). This results in two DNA strands with complementary sequences that can be used for replication and transcription.

The process of DNA replication.
During DNA replication, the template strand is used as a guide to create a complementary copy, while the coding strand is not directly involved in the copying process. The template strand determines the sequence of nucleotides in the new DNA strand, while the coding strand has the same sequence as the RNA transcript that will be produced from the new DNA strand.
During transcription, only one DNA strand is used as a template to synthesize an mRNA molecule. This strand is called the template or antisense strand. The other DNA strand, known as the coding or sense strand, is not used because it has the same sequence as the mRNA molecule being produced, except with thymine instead of uracil. Transcribing both strands would be redundant and energetically wasteful.
