59. The primary structural feature that prevents mRNA from forming extensive, permanent double-stranded helices like DNA is its

A. L-shaped folding pattern
B. Single-stranded linear nature
✓
C. Shorter nucleotide sequence length
D. High concentration of modified nitrogenous bases

📝 Explanation

Being single-stranded without a permanent complementary partner allows mRNA to remain dynamic and easily accessible to ribosomes.

📖 Additional Information

  • L-shaped folding pattern
  • Single-stranded linear nature
  • Shorter nucleotide sequence length
  • High concentration of modified nitrogenous bases

Being single-stranded without a permanent complementary partner allows mRNA to remain dynamic and easily accessible to ribosomes.
