Select and explain. 
A. 10-24 nucleotides, B. 24-46 nucleotides, C. 74-95 nucleotides, D. 96-120 nucleotides
C: 74-95 nucleotides
Answer: C: 74-95 nucleotides 
Explanation: tRNA molecules vary in length from 74 to 95 nucleotides, like many other RNAs, are also generated by nuclear processing of a precursor molecule.Ref: Harper&;s Biochemistry; 30th edition; Chapter 34; Nucleic Acid Structure & Function
