Use complementary base pairing to determine the RNA strand that would be made from the DNA template strand: AAC - TAG - CCA

• TTC - ATG - GGT

• CCT- GCA - AAC

• UUG - AUC - GGU

• TTG - UTC - GGT

Answer explanation

There is no T in RNA - Replaced by U

What is the process by which mRNA is decoded into a protein?

• Transcription

• Translation

• Replication

• Reverse transcription

Answer explanation

Transcription: DNA -> RNA

Translation: RNA -> Protein

What is the purpose of tRNA?

• It is the intermediate between DNA and Protein

• It makes up half of the ribosome

• It carries an amino acid and corresponding anticodon to the ribosome

• It replicates more RNA
