List of top Zoology Questions on Structure of DNA and RNA asked in CUET (PG)

Based on the context given below, answer the following questions:
DNA in eukaryotes is a double-helical structure with two anti-parallel strands intertwined equidistantly. The double-helical structure was deciphered by James Watson and Francis Crick on the basis of X-ray diffraction studies. The hydrophilic backbones of alternating sugar and phosphate groups are on the outside of the helix held together by phosphodiester bonds. The purine and pyrimidine bases of both the strands are stacked inside the double helix. Adenine binds with thymine with hydrogen bond and cytosine binds with guanine with hydrogen bond. The DNA is transcribed into messenger RNA, ribosomal RNA and transfer RNA. Messenger RNA is translated into protein in the cytoplasm.
