The mrna molecule moves from the cytoplasm to the nucleus and binds to a ribosome where it directs the synthesis of specific proteins. a. trueb. false

False

Explanation:

Replication and transcription of the DNA takes place in the nucleus of the cell. So mRNA is produced in the nucleus of the cell and are transported outside the nucleus through the nuclear pore in the cytoplasm.

Cytoplasm is the site where the translation of the mRNA takes place. During translation, ribosomes bind on the mRNA and allow tRNA to add amino acids according to the complementary triplet codon sequence present on the mRNA. So proteins are synthesized in cytoplasm so the statement is false.
