Quick Summary

The template strand in genetics refers to one of the two strands of a DNA molecule that serves as a pattern for the synthesis of a new, complementary strand during DNA replication. This process, known as semiconservative replication, ensures that genetic information is accurately copied and passed down through generations. The structure of DNA, a double helix composed of two antiparallel strands, facilitates this templating mechanism. Each strand's sequence of nucleotides (adenine, thymine, guanine, and cytosine) dictates the sequence of nucleotides in the newly synthesized strand, with adenine pairing with thymine and guanine pairing with cytosine. This precise pairing is fundamental to the faithful transmission of genetic material.12

transcription
This is called the template strand, and the RNA molecules produced are single-stranded messenger RNAs (mRNAs). The DNA strand that would correspond to the mRNA is called the coding or sense strand. In eukaryotes (organisms that possess a nucleus) the initial product of transcription is called a pre-mRNA.
