Question 10
The molecule labelled X represents A. ligase. B. a ribosome. C. RNA polymerase. D. DNA polymerase.
Worked Solution & Example Answer:The molecule labelled X represents A - VCE - SSCE Biology - Question 10 - 2009 - Paper 1
Step 1
C. RNA polymerase.
Answer
The molecule labeled X is RNA polymerase. This enzyme is crucial for the process of transcription, where it synthesizes RNA from a DNA template. RNA polymerase initiates the transcription by binding to the promoter region of a gene, unwinding the DNA helix and catalyzing the formation of an RNA strand complementary to the DNA template.
