DNA dependent RNA polymerase catalyzes transcription on one strand of the DNA, which is called:
Correct answer: A. Template strand
- A. Template strand
- B. Coding strand
- C. Alpha strand
- D. Anti-strand
Explanation
The template strand serves as the template for RNA synthesis (transcription). It is also known as the antisense strand. During transcription, an enzyme called RNA polymerase reads the template strand and synthesises a complementary RNA molecule. The resulting RNA molecule is complementary to the template strand, with the exception of using uracil (U) in place of thymine (T) in RNA. The strand of DNA on which RNA polymerase binds to catalyse transcription is called the template strand. It is also known as the master or antisense strand. It has a polarity of 3' ➡ 5'.

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.
