Protein Synthesis

In mRNA, each codon specifies a particular 

• nucleotide
• amino acid
• purine
• pyrimidine

An mRNA molecule is produced in which step of protein synthesis:

• replication

• transcription

• duplication

• translation

. What are the building blocks of proteins called?

• nucleotides
