Solution
The answer is the last one: mRNA, tRNA, and rRNA are all produced by transcription.
Explanation for each option:
mRNA: Correct, mRNA (messenger RNA) is produced by transcription as it carries the genetic information from DNA to the ribosome for protein synthesis.
rRNA: Correct, rRNA (ribosomal RNA) is also produced by transcription and forms a major part of the ribosome's structure and function.
tRNA: Correct, tRNA (transfer RNA) is produced by transcription and is essential for translating the mRNA sequence into amino acids during protein synthesis.
mRNA and tRNA: Partially correct, but it excludes rRNA, which is also produced by transcription.
mRNA and rRNA: Partially correct, but it excludes tRNA, which is also produced by transcription.
mRNA, tRNA, and rRNA are all produced by transcription: Correct, as all three types of RNA are synthesized from DNA templates through the process of transcription.
Summary:
Transcription is the process by which all three types of RNA (mRNA, tRNA, and rRNA) are synthesized from DNA templates. Therefore, the correct answer is that mRNA, tRNA, and rRNA are all produced by transcription.
