Question

1. all three major types of rna (mrna, trna and rrna) are processed before they are mature. they are derived from precursor rna molecules that are considerably longer than the final rna product. these precursor rnas are called a. pre - rnas. b. transcription factors. c. prions. d. nucleosides. e. both a and b are correct answers.

Explanation:

Pre - RNAs are precursor RNAs that are processed to form mature mRNAs, tRNAs and rRNAs. They are longer than the final RNA products. Transcription factors are involved in the transcription process but are not pre - RNAs. Prions are misfolded proteins and nucleosides are components of nucleotides, not pre - RNAs.

Answer:

a. pre - RNAs.
