Question

What is the three-dimensional shape of tRNA in its actual cellular conformation?

Options

• An inverted L

• A double helix

• A cloverleaf

• A spherical structure

Answer 1

While the secondary structure of tRNA resembles a cloverleaf in two dimensions, its actual three-dimensional structure is a compact molecule shaped like an inverted L. This three-dimensional conformation is essential for its proper function as an adapter molecule in translation.
