I think its B i hope it helps
Answer:
Its translation the third one.
Explanation:
This process is when mRNA comes out of nucleus from nucleus pores and goes to free ribosomes or RER ribosomes. Then the mRNA enters ribosome. each three codes on mRNA is a code of amino acid. then an amino acid chain will be produced.
This chain will fold until it gets to its fourth structure. At last the protein is produced.
The senthesis and replication are not related to protein production.
Its related to cell cycle.
Transcription happens inside nucleus when RNApolymraze transcripts a copy of one strand of DNA
What it makes is mRNA.
Hope you understand.
