Question

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

Explanation:

Transcription is a biological process. In this process, DNA (located in the nucleus) is used as a template to synthesize RNA. The first option describes DNA replication (copying DNA to DNA). The second and third options describe translation (ribosomes using mRNA and tRNA to build proteins). Only the last option correctly defines transcription as the process of copying DNA into RNA.

Answer:

the process by which DNA from the nucleus is copied into RNA.
