Messenger RNA differs from transfer RNA in that mRNA
Correct answer: A. carries a copy of the base sequence of a gene from the nucleus to the ribosome
- A. carries a copy of the base sequence of a gene from the nucleus to the ribosome
- B. is folded into a clover leaf shape
- C. carries an anticodon at one end
- D. is the most abundant type of RNA in the cell
Explanation
Messenger RNA is transcribed from one strand of a gene and is read in triplets by the ribosome, so its length varies with the gene it copies and it is usually short lived. The clover leaf shape and the anticodon belong to transfer RNA, and ribosomal RNA is the most abundant type by mass. Because mRNA is a working copy, the original DNA is never exposed to the risks of the cytoplasm.

About Ribonucleic Acid (RNA)
Ribonucleic acid is generally a single-stranded nucleic acid containing ribose and uracil instead of thymine. Coverage includes mRNA, tRNA and rRNA, complementary base pairing, transcription and translation, and the differences between RNA and DNA in structure, location and biological function.
