Grade 9 gradeScience subjectFree quiz

Grade 9 DNA, RNA, and protein synthesis follow the central dogma: DNA is replicated, transcribed to mRNA, and translated to a polypeptide. Students use base-pairing rules, distinguish the three main RNA types, and connect a mutation to a possible amino-acid change. Codons are read in triplets on mRNA.

What you practice

These are the Grade 9 DNA, RNA & Protein Synthesis skills this quiz is built around.

Apply base-pairing rules (A with T, G with C in DNA; U replaces T in RNA).
Outline replication, transcription, and translation in the correct order.
Predict how a substitution mutation could change, or fail to change, an amino acid.

A useful tip

Transcription copies DNA into complementary mRNA in the nucleus of eukaryotic cells. Translation reads that mRNA at a ribosome to build a protein. Mixing those locations is a common mix-up.
