State that the strand of a DNA molecule that is used in transcription is called the transcribed or template strand and that the other strand is called the non-transcribed strand

• The strand of a DNA molecule used in transcription:
  • Name: Transcribed Strand or Template Strand
  • Characteristics:
    • Serves as the template for mRNA synthesis
    • Runs in the 3′ to 5′ direction during transcription
    • Read by RNA polymerase to guide the formation of a complementary RNA strand
    • Also known as the Antisense Strand, Non-Coding Strand, or Minus Strand
• The other strand of the DNA molecule (not used in transcription for a particular gene):
  • Name: Non-Transcribed Strand
  • Characteristics:
    • Does not directly participate in the formation of mRNA for a specific gene
    • Sequence is identical to the mRNA transcript (except for Uracil in RNA instead of Thymine in DNA)
    • Runs in the 5′ to 3′ direction when considering its own sequence
    • Also known as the Coding Strand, Sense Strand, or Plus Strand
