5 Questions

What are the two types of RNA molecules produced during transcription?

messenger RNA (mRNA) and non-coding RNAs (ncRNAs).

What is transcription?

Transcription is the process of copying a segment of DNA into RNA.

What is the role of RNA polymerase during transcription?

RNA polymerase reads a DNA sequence and produces a complementary, antiparallel RNA strand called a primary transcript.

What percentage of total RNA samples does mRNA comprise?

mRNA comprises only 1–3% of total RNA samples.

What are the general steps of transcription?

RNA polymerase binds to promoter DNA, generates a transcription bubble, adds RNA nucleotides, and forms an RNA strand with assistance from RNA polymerase.

Test your knowledge of transcription and RNA with this quiz. Explore the process of copying DNA into RNA, the role of messenger RNA (mRNA) in protein synthesis, and the significance of non-coding RNAs (ncRNAs). Learn about the proportion of mRNA in total RNA samples and the percentage of the human genome transcribed into mRNA.
