Final answer:
The template strand, also known as the antisense strand or Crick strand, is the strand of DNA that serves as the template for RNA synthesis. It provides the complementary sequence that guides the formation of mRNA during transcription.
Step-by-step explanation:
The template strand, also known as the antisense strand or Crick strand, is the strand of DNA that serves as the template for RNA synthesis. It provides the complementary sequence that guides the formation of mRNA during transcription. The template strand is read in the 3' to 5' direction, while the newly synthesized mRNA is formed in the 5' to 3' direction.
