Which shows the correct complementary base pairing for DNA?

• C-A, T-G
• A-G, C-T
• C-G, U-A
• T-A, G-C

The process of making RNA (i.e. mRNA) from DNA is called

• Replication
• Transcription
• Translation
• Protein synthesis

Where does Translation take place?

• RNA
• ribosome
• nucleus
• chromosome

Transcription takes place in the 

• cytoplasm
• chloroplast
• nucleus
• mitochondria

This cannot leave the nucleus

• DNA
• RNA
• Both

Which is the mRNA molecule that would be transcribed from this DNA template:
TGGCAA

• ACCGTT
• UGGCAA
• UCCGUU
• ACCGUU

What is the job of tRNA in protein synthesis?

• It is the blueprint of the genetic code
• it reads the mRNA
• it brings Amino Acids to the ribosome
• it is not involved in protein synthesis

mRNA is important, because it __________.

• Carries info from genes to ribosomes
• Carries amino acids to ribosomes
• Helps with RNA splicing
• Makes up ribosomes
