Question

the process by which ribosomes read trna in order to build proteins.
the process by which dna from the nucleus is copied into more dna.
the process by which dna from the nucleus is copied into rna.
the process by which ribosomes read mrna in order to build proteins.

Explanation:

Translation is the process where ribosomes read mRNA (messenger RNA) to build proteins. tRNA (transfer RNA) brings amino acids to the ribosome based on the mRNA sequence. DNA replication is when DNA is copied into more DNA. Transcription is when DNA is copied into RNA. The first option has an incorrect molecule (tRNA instead of mRNA). The second is DNA replication. The third is transcription. The fourth correctly describes translation.

Answer:

the process by which ribosomes read mRNA in order to build proteins.
