Final answer:
The statement that the initial attachment of the transcription enzyme to the gene results in a structure known as the closed complex is true. In transcription initiation, transcription factors and RNA polymerase form this complex before DNA is completely unwound to begin RNA synthesis.
Step-by-step explanation:
The initial attachment of the transcription enzyme to the gene does indeed result in a structure termed the closed complex. This statement is true. During the initiation phase of transcription, the transcription factors and RNA polymerase bind to the promoter of the DNA to form an initiation complex. Once RNA polymerase is secured onto the promoter region, DNA unwinding creates a transcription bubble.
The DNA at this stage is not yet fully unwound, which characterizes the closed complex. It is only after RNA polymerase binds more tightly, and the DNA is unwound to about 17 base pairs, that an 'open complex' is formed, clearing the way for RNA synthesis.
