Question

Select correct statement from the following.

• A. In a DNA molecule, the two strands are antiparallel and non complementary
• B. The rRNA is always present in variously folded form
• C. During DNA replication, leading strand is formed in $3^{\prime }\to 5^{\prime }$ while lagging strand is formed in $5^{\prime }\to 3^{\prime }$ direction
• D. The mRNA molecule may be straight or coiled upon itself to form a hairpin like shape

Answer 1

Answer: (B)

The rRNA is always present in variously folded form

• rRNA (ribosomal RNA) is synthesized in the nucleolus. rRNAs combines with ribosomal proteins to form the ribosome.
• The rRNAs from folded secondary structures to recognize mRNAs and tRNA during protein synthesis.

Thus the correct answer is option B.
