Multiple choice bio-chemistry nucleic acids central dogma transcription and gene expression molecular biology

Central dogma of protein synthesis consists of

  1. $DNA \overset{translation}{\rightarrow} mRNA \overset{transcriptionlation}{\rightarrow} Protein$
  2. $DNA \overset{transcription}{\rightarrow} mRNA \overset{translation}{\rightarrow} Protein$
  3. $RNA \overset{replication}{\rightarrow} DNA \overset{translation}{\rightarrow} Protein$
  4. $RNA \overset{transcriptions}{\rightarrow} mRNA \overset{translation}{\rightarrow} Protein$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The central dogma states that genetic information flows from DNA to RNA via transcription, and from RNA to protein via translation.

Which one is RNA dependent DNA polymerase

  1. RNA polymerase I

  2. Tag polymerase

  3. DNA polymerase

  4. Reverse transcriptase

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Reverse transcriptase is the RNA-dependent DNA polymerase that synthesizes DNA from an RNA template. RNA polymerase I and DNA polymerase are not RNA-dependent. Tag polymerase appears to be a typo (likely Taq polymerase), which is a DNA-dependent DNA polymerase used in PCR.
