What is true about part A?
mRNA is made from DNA
Proteins are made from amino acids
This takes place in the ribosome/cytoplasm
This is where tRNA anticodons pair with mRNA codons

This occurs in the nucleus
mRNA is made here
DNA remains here
tRNA brings amino acids to mRNA at the ribosome where proteins are assembled
