Question

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

Explanation:

Translation is a biological process. In this process, ribosomes play a crucial role. Ribosomes read mRNA (messenger RNA). The genetic code in mRNA is used to assemble amino acids into proteins. tRNA (transfer RNA) brings the appropriate amino acids to the ribosome based on the mRNA sequence. The first option describes DNA replication (copying DNA to DNA). The fourth option describes transcription (copying DNA to RNA). The second option has an error as ribosomes read mRNA, not tRNA directly for building proteins in the context of translation.

Answer:

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