Which of the following RNAs up specific amino acid (from amino acid pool) in the cytoplasm to ribosome during protein synthesis
Or
Which form of RNA has a structure resebling clover leaf

Options

A. mRNA
B. tRNA
C. rRNA
D. RNA

Answer

B

Explanation

tRNA (soluble RNA = sRNA) is a 70-75 nucleotide ling molecule . 80% of this RNA is double helical , one end of this molecule has G and other C- C- A sequences.
The clover leaf model [2D) of tRNA was given by R Holley [1968] and Kim et al , [1873] suggested 'L' shaped model (3D] of tRNA by X- ray diffraction while studying phenyl alanine tRNA of yeast . Each amino acid had its own specific tRNA molecule which transfers it from cytoplasm to the ribosome.
