Which of these has the smallest molecular weight?

Question

Quizplus · Accepted Answer

tRNA (transfer RNA) is a small RNA molecule that carries amino acids to the ribosome during protein synthesis, and has a molecular weight of about 25,000-30,000 Da. mRNA (messenger RNA) is larger and carries genetic information from DNA to the ribosome, with a molecular weight of about 2-4 million Da. rRNA (ribosomal RNA) is a structural component of the ribosome and has a molecular weight of about 1-3 million Da. DNA (deoxyribonucleic acid) is a large molecule that carries genetic information and has a molecular weight of about 100 million Da.
