B
False
Verified step by step guidance
1
Understand the process of transcription: Transcription is the process by which the information in a gene's DNA is transferred to a messenger RNA (mRNA) molecule.
Identify the role of DNA strands: DNA is double-stranded, consisting of a 'template strand' and a 'coding strand'.
Determine which strand is used: During transcription, only the template strand of DNA is used to synthesize mRNA. The template strand is complementary to the mRNA sequence.
Clarify the role of the coding strand: The coding strand is not used in the transcription process but has the same sequence as the mRNA (except for thymine being replaced by uracil in RNA).
Conclude the statement: Since only the template strand is used during transcription, the statement 'Only one strand of DNA is used during transcription of a gene' is true.
