In a labeled diagram of transcription, enzyme "X" synthesizing RNA is:
Correct answer: B. RNA polymerase
- A. DNA polymerase
- B. RNA polymerase
- C. Ligase
- D. Helicase
Explanation
RNA polymerase reads the DNA template strand and synthesizes a complementary RNA strand. DNA polymerase is used in replication, not transcription. Ligase joins DNA fragments, while helicase unwinds DNA strands.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
